Dangerous fish in the Amazon. Animals of the Amazon: “Fauna of the Amazon Forests. The most dangerous animals of the Amazon

The Amazon originates at an altitude of 5 thousand meters from the snow-capped peaks of the Peruvian Andes. Gradually, flows melt water flow down to form a river. At such heights, there are practically no inhabitants in the river, but there are exceptions. The clawed duck (Merganetta armata) thrives in cold, turbulent streams.

Driven by the force of gravity, the river makes its way through the mountain ranges, washing away the sediment from the mountain ranges along the way. Soon the Amazon falls into the humid mountain forests. These forests are one of the wettest places on the planet. Clouds and mists collide with the mountain slopes, and 6 meters of precipitation falls here annually. Passing through the mountain gorges, the Amazon forms numerous waterfalls.

This is the realm moist forests located at an altitude of 3.5 thousand meters, here the Amazon continues to gain its power. survive in such humid climate also not easy. But many plants take advantage of this dampness, they do not need soil moisture and therefore they can grow directly on tree trunks. Hummingbirds and other birds act as pollinators instead of insects. It is home to the largest variety of hummingbird species in the world. Each species has a beak adapted to specific tasks, birds and plants complement each other perfectly. Another amazing creature lives here - the smallest in the world and the only one in South America a bear called the spectacled bear (Tremarctos ornatus). Monkeys don't climb that high.

Descending lower and lower, the Amazon finally reaches the foot of the Andes. Here the river slows down its turbulent course and spreads over a wide plain.

At the Peruvian city of Iquitas, the river gets its name Amazon. Already here, the width of the river reaches 2 km, and the average depth of the river is 100 meters. Despite the fact that this place is 3.5 thousand meters away from the Atlantic Ocean, ships sail here. From here, the river will flow across the plain, making its way through the world's greatest tropical jungle with an area of ​​7 million km. sq.

The river is full of minerals brought from the mountain peaks, and they settle on the river banks. These minerals provide many benefits to the wild animals and fish of the Amazon. For example, Ara parrots cannot imagine life without them. This clay helps the Macaws get rid of the poison they eat along with plant seeds.

A huge number of unique and unusual animals live in the intricacies of the arms and tributary of the Amazon basin. The diversity is striking flora in the Amazon and the underwater world of the river.

Brazilian, or giant otter (lat. Pteronura brasiliensis). Likes quiet backwaters, grows up to 2 meters in length. One of the largest predators of the Amazon. It can even eat a boa constrictor or a python for lunch. Giant otters live in large family clans.

The wedge-bellied or flying fish of the Amazon. Fleeing from predators, it can jump 120 cm out of the water with the help of well-developed pectoral fins.

The Sun Heron is a master of bluffing and can scare off many predators with her unusual plumage.

The Amazon is replete with old women. There is no longer a current and the plants grow in full force. The most successful in this business is the giant Amazonian lily, or as it is also called Victoria Regia, its leaves reach 2 meters in diameter.

Giant Amazonian lily or Victoria Regia. As you can see, you can sleep on it without even getting your feet wet.

Floating plants on the river form a kind of floating mobile islands, these lawns drift carried away by the river current. Their diameter can be many times greater than 100 meters. Not only plants, but also animals live on these rafts. They are home to the largest animal in South America - the manatee. The weight of a manatee can reach 500 kg, and a length of 3 meters.

The world's largest rodent, the capybara (Hydrochoerus hydrochaeris), also lives here.

Amazonian caimans play the role of a crocodile here, caimans eat capybaras with pleasure. Also, these rodents should beware of the anaconda.

Video: Anaconda catches and eats a capybara.

Every year before the start of the rainy season, the water level in the Amazon drops to a minimum. A large number of closed lagoons are formed. This is the most difficult time of the year for the fish, it is trapped. But predators are feasting with might and main, fishing at this time of the year is very simple fish can be fished without much effort.

There are 20 species of piranha in the Amazon, but the red piranha is the most ferocious of them all. If these monsters are locked in a water trap, then they first destroy all life around them, and then real cannibalism begins. After such a "massacre" only the strongest individuals remain alive.

During the Doge season, the water level in the river will rise sharply. For the fish finally come Good times. The Amazon Basin is literally a pool. The Amazon does not have time to dump excess water into the Atlantic Ocean and overflows its banks. On such a large river, the flood should be large. The river overflows and floods everything around at a distance of 80 km on both sides of its banks. Trees are flooded to a depth of 16 meters. The area of ​​flooded land can be compared with the area of ​​England. Fish rush after the flood. Here for fish there is a lot of food, and for every taste. Most likely, this explains the diversity of the underwater world of the Amazon. There are more than 3,000 species of fish in the river, which is more than in the Atlantic Ocean.

Not surprisingly, the Amazon is home to the largest freshwater fish in the world, the Arapaima or Pirarucu (Arapaima gigas). This giant fish has a semblance of a lung, and from time to time it emerges to breathe fresh air. The weight of Arapaima can reach 200 kg.

The largest freshwater fish in the world - Arapaima or Pirarucu (Arapaima gigas)

Other unusual creatures live in the middle of the flooded forests. For example, a blind pink penguin (Amazon dolphin, or white river dolphin) lives here, to catch fish follow the thickets, he uses echolocation.

Trees can stay under water for six months of the year, so the river and fish carry the seeds here.

Another unusual local animal is the bald wakari. These monkeys can eat fruits of any maturity.

Bald wakari.

There are also fish that jump out of the water during the mating season. Tetra jumps out of the water and leaves eggs on the leaves of trees. The male will moisten it with water until the fry hatch.

Fire ants have a hard time during the flood, they all gather together and form a living raft, connecting with each other. They are carried away by the current, and the only hope for salvation is if they are washed ashore.

Fire ants huddled together.

People have also adapted to such fluctuations in water levels and live on rafts.

It is also home to giant river turtles, the largest river turtles on the planet, for a million years. Their shell is over a meter in diameter.

The giant arapaima is one of the largest and least studied fish in the world. Those descriptions of fish that are found in the literature are borrowed mainly from the unreliable stories of travelers.

It is even strange how little has been done so far to deepen our knowledge of the biology and behavior of the arapaima. For years, it has been hunted mercilessly both in the Peruvian and Brazilian parts of the Amazon, and in its many tributaries. At the same time, no one cared about studying it and did not think about preserving it. Schools of fish seemed inexhaustible. And only when the number of fish began to noticeably decrease, interest in it appeared.

Arapaima is one of the largest freshwater fish in the world. Representatives of this species live in the Amazon in Brazil, Guyana and Peru. Adults reach 2.5 m in length and weigh up to 200 kg. The uniqueness of the arapaima is the ability to breathe air. Due to their archaic morphology, the fish is considered a living fossil. In Brazil, fishing is allowed only once a year. Initially, the fish was harvested with the help of harpoons when it rose to breathe on the surface.

Today it is caught mainly with nets. Let's take a look at this in more detail..

In Brazil, giant fish have been placed in ponds in the hope that they will take root there. In eastern Peru, in the jungles of the province of Loreto, certain areas of rivers and a number of lakes are left as a reserve fund. It is allowed to fish here only under the license of the Ministry Agriculture.

Arapaima lives throughout the Amazon basin. To the east, it occurs in two areas separated by the black and acidic waters of the Rio Negro. Arapaima is not found in Rio Negro, but the river, apparently, is not an insurmountable barrier for fish. Otherwise, one would have to assume the existence of two species of fish, having different origins and living north and south of this river.

The western distribution area of ​​\u200b\u200bthe arapaima is probably Rio Morona, to the east of it, Rio Pastaza and Lake Rimachi, where a huge amount of fish is found. This is the second protected reservoir in Peru for breeding and observing arapaima.

The adult arapaima is painted very picturesquely: the color of its back changes from bluish-black to metallic green, the belly - from cream to greenish-white, the sides and tail are silver-gray. Each of its huge scales shimmers with all sorts of shades of red (in Brazil, the fish is called pirarucu, which means red fish).

Swinging in time with the movements of the fishermen, a small canoe floated along the mirror-like surface of the Amazon. Suddenly, the water at the bow of the boat began to swirl, the mouth of a giant fish stuck out, exhaling air with a whistle. The fishermen stared dumbfounded at the monster two human heights long, covered with a scaly shell. And the giant splashed his blood-red tail - and disappeared into the depths ...

Tell such a Russian fisherman, he will immediately be ridiculed. Who is not familiar with fishing tales: either a giant fish will fall off the hook, or the local Nessie will be seen. But on the Amazon, meeting a giant is a reality.

Arapaima is one of the largest freshwater fish. There were specimens 4.5 m long! Now you don't see them. Since 1978, the record of the Rio Negro River (Brazil) has been held, where they caught arapaima with data of 2.48 m - 147 kg (the price of a kilogram of tender and tasty meat, which has almost no bones, far exceeds the monthly income of Amazonian fishermen. AT North America it can be seen in antique shops).

This strange creature looks like a representative of the era of dinosaurs. Yes, it is true: a living fossil has not changed in 135 million years. Tropical Goliath has adapted to the marshy swamps of the Amazon basin: the bladder attached to the esophagus acts as a lung, the arapaima protrudes from the water every 10-15 minutes. She, as it were, “patrols” the Amazon basin, captures small fish in her mouth and grinds them with the help of a bony, rough tongue (locals use it as sandpaper).

Photo 5.

These giants live in the freshwater reservoirs of South America, in particular in the eastern and western parts of the Amazon basin (in the Rio Morona, Rio Pastaza and Lake Rimachi rivers). In these places there is a huge number of arapaima. In the Amazon itself, this fish is not so much, because. she prefers quiet streams with a weak current and a lot of vegetation. A pond with indented banks and a large number of floating plants - that's perfect place for its habitation and existence.

Photo 6.

According to local residents, this fish can reach 4 meters in length and weigh about 200 kilograms. But arapaima is a valuable commercial fish, so now you can hardly find such huge specimens in nature. In our time, most often come across specimens no more than 2-2.5 meters. But still, giants can be found, for example, in special aquariums or reserves.

Photo 7.

Previously, arapaima were caught in large quantities and did not think about its population. Now, when the stocks of these fish have noticeably decreased, in some countries of South America, for example, in eastern Peru, areas of rivers and lakes have been identified that are strictly protected and fishing in these places is allowed only under license from the Ministry of Agriculture. Yes, but in limited quantities.

Photo 8.

An adult can reach 3-4 meters. The powerful body of the fish is covered with large scales, which shimmer with various shades of red. This is especially noticeable in its tail. For this, the locals gave the fish another name - piraruku, which translates as "red fish". The fish themselves have a different color - from "green metallic" to bluish-black.

Photo 9.

Her very unusual respiratory system. The pharynx and swim bladder of fish are covered with lung tissue, which allows the fish to breathe. ordinary air. Such an adaptation has developed due to the low oxygen content in the waters of these freshwater rivers. Thanks to this, arapaima can easily survive the drought.

Photo 10.

You can't confuse the breathing pattern of this fish with anyone else. When they rise to the surface for a breath of fresh air, small whirlpools begin to form on the water surface, and then the fish itself appears at this place with a huge open mouth. All this action lasts just a couple of seconds. She releases the "old" air and takes a new sip, her mouth closes abruptly and the fish goes to the depths. Adults breathe like this every 10-15 minutes, young ones a little more often.

Photo 11.

On the head of these fish are special glands that secrete a special mucus. But what it is for, you will find out a little later.

Photo 12.

These giants feed on bottom fish, sometimes they can eat small animals, such as birds. In juveniles, freshwater shrimp are the main dish.

Photo 13.

The breeding season for pyrarucu is in November. But they begin to create pairs already in August-September. These giants are very caring parents, especially males. Then I immediately remembered how the male "sea dragons" take care of their offspring. These fish are not far behind. The male digs a shallow hole with a diameter of about 50 centimeters near the shore. The female lays her eggs in it. Then, throughout the entire period of development and maturation of eggs, the male is next to the clutch. He guards the eggs and swims near the "nest", while the females at this time drive away the fish swimming nearby.

Photo 14.

A week later, fry are born. The male is also next to them. Or maybe they are with him? The young are kept in a dense flock near his head, and even to breathe they rise together. But how does a male manage to discipline his kids like that? There is a secret. Remember, I mentioned special glands on the head of adults. So, the mucus that is secreted by these glands contains a stable substance that attracts fry. It is what makes them stick together. But after 2.5-3 months, when the young grow up a little, these flocks break up. The bond between parents and children is weakening.

Once the meat of these monsters was the staple food of the peoples of the Amazon. Since the late 1960s, in many rivers, arapaims have disappeared completely: after all, only large fish were killed with a harpoon, while the nets also made it possible to catch babies. The government has banned the sale of arapaime less than a meter and a half long, but the taste, which only trout and salmon can compete with, pushes people to break the law. Arapaima breeding in artificial pools with heated water is promising: they grow as much as five times faster than carps!

Photo 15.

However, here is the opinion of K. X. Lyuling:

The literature of past years greatly exaggerates the size of the arapaima. To some extent, these exaggerations began with the descriptions of R. Schomburk in the book Fishes of British Guiana, written after a trip to Guiana in 1836. Schomburk writes that fish can reach a length of 14 feet (foot = 0.305 meters) and weigh up to 400 pounds (pound = 0.454 kilograms). However, this information was obtained by the author secondhand - from the words of the local population - he personally did not have evidence to confirm such data. In a well-known book on the fish of the world, McCormick expresses doubts about the authenticity of these stories. After reviewing all available and more or less reliable information, he concludes that members of the arapaima species never exceed 9 feet in length, a fairly substantial size for a freshwater fish.

My own experience convinced me that McCormick was right. The animals we caught in Rio Pacay averaged 6 feet in length. The largest fish was a female 7 feet long and weighing 300 pounds. Obviously, the illustration from the old editions of Brehm's Animal Life, which depicted an Indian sitting on the back of a pyrarucu, 12 to 15 feet long, should be considered sheer fantasy.

The distribution of arapaima in certain areas of the river apparently depends more on the vegetation growing there than on the nature of the water itself. For fish, a heavily indented coast with a wide strip of coastal floating plants is needed, which, intertwined, form floating meadows.

For this reason alone, fast-flowing rivers like the Amazon are unsuitable for the existence of the Arapaima. The bottom of the Amazon always remains smooth and uniform, so there are few floating plants, the ones that are usually tangled among shrubs and hanging branches.

On Rio Pacai we found arapaima in backwaters, where, in addition to floating meadows of aquatic grasses, floating mimosas and hyacinths grew. In other places, these species may have been replaced by floating ferns, victoria-regia, and some others. The giant fish is invisible between the plants.

It is perhaps not surprising that arapaims prefer to breathe air rather than the oxygen of the swampy waters in which they live.

Photo 16.

Arapaima's manner of inhaling air is very characteristic. When it comes to the surface big fish, first a whirlpool forms on the water surface. Then suddenly the fish itself appears with its mouth open. She quickly releases air, making a clicking sound, inhales fresh air and immediately sinks into the depths.

According to the whirlpool formed on the surface of the water, fishermen hunting for arapaima determine where to throw the harpoon. They throw their heavy weapons right into the middle of the whirlpool and most of the time they miss their target. But the point is that giant fish often lives in small reservoirs, 60-140 meters long, and whirlpools are constantly formed here, and therefore, the likelihood of a harpoon hitting an animal increases. Adults appear on the surface every 10-15 minutes, young ones more often.

Having reached a certain size, arapaima moves to the fish table, specializing mainly in bottom armored fish. In the stomachs of arapaima, the prickly needles of the pectoral fins of these fish are most often found.

In Rio Pakai, obviously, the conditions for the life of arapaima are the most favorable. The fish living here reach maturity within four to five years. By this time they are about six feet long and weigh between 80 and 100 pounds. It is believed (although not proven) that some, and possibly all, adults breed twice a year.

Once I was lucky enough to watch a pair of arapimes preparing to spawn. Everything happened in the clear and still waters of the quiet bay of Rio Pakai. The behavior of arapaima during spawning and their further care for offspring is truly an amazing sight.

Photo 17.

In all likelihood, the spawning hole in the soft clay bottom of the fish is pulled out by mouth. In the quiet bay where we made our observations, the fish chose to spawn at a depth of only five feet below the surface. For several days, the male was within this place, and the female almost all the time kept 10-15 meters from him.

The young, hatched from the eggs, remain in the hole for about seven days. Next to them is constantly a male, either circling over the hole, or perched on the side. After that, the fry rise to the surface, relentlessly following the male and keeping in a dense flock near his head. Under the supervision of the father, the whole flock floats to the surface at once to inhale the air-Spirit.

At the age of seven to eight days, the fry begin to feed on plankton. Watching the fish through the still waters of our quiet bay, we did not notice that the fish were rearing young growth "in vtu", that is, they would take the fish in their mouths in a moment of danger. There were also no signs that the larvae feed on a substance secreted from the platelike gills located on the heads of the parents. The local population makes a clear mistake, assuming that the young are fed by parental "milk".

In November 1959, I was able to count 11 schools of young fish in a lake of about 160 acres (an acre is about 0.4 hectares). They swam close to the shore and parallel to it. The flocks seemed to avoid the wind. This is probably due to the fact that the waves formed by the wind make it difficult to inhale air from the surface of the water.

We decided to see what would happen to a flock of fish if it suddenly lost its parents, and caught them. The orphaned fish, having lost contact with their parents, obviously lost contact with each other. The tight flock began to disintegrate and eventually dispersed. After some time, we noticed that the juveniles in other flocks differ significantly from each other in size. Such a large contrast could hardly be explained by the fact that the same generation of fish developed differently. Apparently, other Arapaima adopted orphans. Expanding the circle of swimming after the death of their parents, the orphaned flock of fish spontaneously mixed with neighboring groups.

Photo 18.

On the head of the arapaima there are glands of a very interesting structure. Outside, they have a number of small, tongue-like protrusions, at the ends of which, with a magnifying glass, tiny holes can be discerned. Through these openings, the mucus formed in the glands is secreted.

The secretion of these glands is not used as food, although this would seem to be the simplest and most obvious explanation for its purpose. It performs much more important functions. Here is an example. When we pulled the male out of the water, the flock accompanying him remained for a long time in the very place from which he had disappeared. And one more thing: a flock of juveniles gathers around a gauze pad, previously soaked in the secretions of the male. From both examples, it follows that the male secretes a relatively stable substance, thanks to which the whole group is held together.

At the age of two and a half - three and a half months, flocks of young animals begin to disintegrate. By this time, the bond between parents and children is weakening.

The Amazon River Basin, also known as the Amazon Rainforest, or Amazonia, covers more than 7 million square kilometers and overlaps the borders of nine countries: Brazil, Colombia, Peru, Venezuela, Ecuador, Bolivia, Guyana, Suriname and French Guiana. By some estimates, this region (which occupies almost 40% of the area of ​​the South American continent) is home to a tenth of the world's animals. In this article, you will discover the most important animals living in the Amazon, from monkeys to poison dart frogs.

Piranha

There are many myths about piranhas including that they can eat a cow carcass in less than 5 minutes or like to attack people. However, there is no doubt that the piranha is made to kill, as it has sharp teeth and extremely powerful jaws. Considering how many people are afraid of the common piranha, they would hardly want to know about giant ancestor piranha - megapiranha, which was 4 times larger than its contemporary.

capybara

The capybara is the largest rodent in the world, growing up to 70 kg. It is widely distributed throughout South America, but is especially fond of the warm, humid surroundings of the Amazon basin. This mammal prefers abundant rainforest vegetation, including fruit, tree bark, aquatic plants, and gathers in social groups of up to 100 individuals.

Jaguar

The third largest representative after lions and tigers. Over the past century, jaguars have faced threats such as deforestation and human encroachment that have limited their range throughout South America. However, jaguars are much more difficult to hunt in the dense forests of the Amazon than in the open, and impenetrable patches of rainforest may be the last resort for these cats. The jaguar is a super predator, being at the top of the food chain, it is not threatened by other animals.

giant otter

Giant otters are the largest members of the mustelid family and are closely related to weasels. Males of this species can reach a length of up to 2 m and a weight of up to 35 kg. Both sexes have thick and shiny coats that are very valuable to poachers. It is estimated that there are only about 5,000 giant otters left in the entire Amazon.

Unusually for mustelids (but fortunately for poachers), giant otters live in large social groups consisting of about 20 individuals.

giant anteater

It has a comically long muzzle - thanks to which it is able to sneak into the narrow holes of insects, as well as a long bushy tail. Some individuals can reach a weight of 45 kg. Like many, the giant anteater is under serious threat, but the swampy, impenetrable Amazon River basin provides some level of protection from human encroachment for the remaining individuals (not to mention an inexhaustible supply of tasty ants).

Golden Lion Marmoset

Golden lion marmoset- small monkey, also known as the golden lion tamarin or rosalia. This primate species has suffered terribly from human encroachment: by some estimates, the ape lost a whopping 95% of its South American habitat with the arrival of European settlers 600 years ago. The golden marmoset weighs no more than one kilogram and has a striking appearance: thick, silky, bright red hair, as well as a dark face, and large brown eyes.

The distinctive color of this primate probably depends on a combination of intense sunlight and the abundance of carotenoids contained in its diet.

black caiman

It is the largest and most dangerous reptile in the Amazon. It is a representative of the alligator family and can reach a body length of about 6 m and a weight of up to 500 kg. Black caimans eat almost anything that moves, from mammals to birds and their reptile cousins. In the 1970s, the black caiman was under serious threat of extinction due to hunting for meat and valuable skin, but its population has since recovered, which cannot bring joy to other animals of the Amazon rainforest.

Dart frogs

Arrow flies are a family of amphibians with 179 species. The brighter the color of the poison dart frogs, the stronger their poison - which is why Amazon predators stay away from bright green or orange species. These frogs do not produce their own poison, but accumulate it from ants, mites, and other insects in their diet (this is evidenced by the fact that poison dart frogs that were kept in captivity and fed on other foods are much less poisonous).

rainbow toucan

The rainbow toucan is one of the most comical animal species in the Amazon. It is characterized by a huge, multi-colored beak that is actually much lighter than it first appears (the rest of the body is not as bright except for the yellow neck). Unlike many of the animals on this list, the rainbow toucan population is of the least concern. This bird jumps from branch to branch and lives in small groups of 6 to 12 individuals. During the mating season, males challenge each other to duels and use their beaks as weapons.

three-toed sloth

Millions of years ago, during the Pleistocene era, the rainforests of South America were home to giant, 4-ton sloths - megatheriums. How things have changed: Today, one of the most common sloths in the Amazon is the three-toed sloth. (Bradypus tridactylus). It has a greenish-brown coat color (due to green algae), limbs with three sharp and long claws, and is also able to swim. This animal is terribly unhurried - its average speed about 16 meters/hour.

The three-toed sloth coexists with two species of the two-toed sloth genus (Choloepus): sloth hoffman (Choloepus hoffmanni) and two-toed sloth or unau (Choloepus didactylus), and they sometimes choose the same trees.

The Amazon rainforest is a huge ecosystem that provides habitat for such unusual and beautiful creatures as the jaguar, poison dart frog and helmeted basilisk. But in this environment live not only animals that prowl, swing and slide through the trees. In the muddy waters of the Amazon River, the deepest river in the entire world, creatures so amazing and terrible live that the sight of their jaws is more terrible than some jaws floating in the marine environment.

10. Black caimans (lat. Melanosuchus niger)

A photo. black caiman

The black caiman is like an alligator pumped on steroids. It can grow up to six meters in size, and has a larger and heavier skull than the same Nile crocodile, and in the Amazonian waters it is at the top of the food chain. This means that they mainly reign in the rivers, they eat almost everything that can get into their teeth, including perches, piranhas, monkeys, anacondas and deer.

And, of course, they are able to attack people, which happens periodically. In early 2010, biologist Diis Nishimura was attacked by a caiman while cleaning fish on her houseboat, and although she managed to fight it off, she lost one of her legs. This particular caiman had been waiting for her under the houseboat for nine months, apparently waiting for the moment to strike.

9. Giant anacondas (lat. Eunectes murinus)

A photo. green anaconda

Continuing the theme of gigantic reptiles, we should recall the largest snake in the whole world that lives in the Amazon: the anaconda. While reticulated pythons are actually considered the longest snakes themselves, green anacondas are much heavier; females are generally larger than their males and can grow up to nine meters (over 29 feet) long, weigh 250 kilograms (550 pounds), and reach 30 centimeters (12 inches) in diameter. Is not Poisonous snakes, but instead of venom, they rely on their enormous muscular strength to grip and strangle their prey, among which you can find capybara, caiman, deer and even jaguar. She likes shallow water, which allows her to stealthily sneak up on her prey. As a rule, these snakes live in the tributaries of the Amazon, and not in the main channel of the river.

8. Arapaima (lat. Arapaima)

A photo. Arapaima caught

Arapaima according to the IGFA world record is the largest fish living in water bodies. Arapaima, also known as "pirarucu" or "paiche", are giant carnivorous fish that live in the Amazon and nearby lakes. Studded with armored scales, they don't mind living in piranha-infested waters, as they are quite agile predators that eat fish and randomly passing birds. As a rule, arapaima are near the surface, because they need to breathe ordinary air, and also receive oxygen from the water with their gills. They make a characteristic cough when they surface. The arapaima's proximity to the surface of the water makes it vulnerable to human hunters, who can easily attack with harpoons. Some indigenous communities consume Arapaima meat and tongue, turning them into jewelry and other items.

They grow up to 2.6 meters in size and gain about 90 kilograms (200 pounds) in weight. These fish are so dangerous that even their tongue is littered with teeth.

7. Giant otters (lat. Pteronura brasiliensis)

A photo. giant otter

The name itself speaks of them, these animals are very large, and these are really very large otters. They are the longest of the 13 otter species, with adult males growing up to two meters (over six feet) in length (from head to tail). It is difficult to distinguish between a male and a female giant otter because there is no fundamental difference in head or body size. This species can make up to nine different sounds and it can be very loud.

Their main food consists of crabs and fish, which they catch in family groups of two to seven individuals, and are capable of eating up to four kilograms (nine pounds) of seafood per day. Don't look at their cute faces, they deserve to be on this list more than any other animal, as it has been observed that in groups they can kill and eat anacondas. They are also able to give a serious rebuff to the caiman. One day, a family of otters was spotted eating a 1.5-meter (5-foot) caiman, which took them approximately 45 minutes. Although their numbers are declining, due in large part to human activity, they are among the most advanced predators in the Amazon rainforest.

However, candiru prefer other fish, with the help of spines they attach themselves inside the gills of larger individuals and feed on the blood of their owner.

5. Blunt sharks (lat. Carcharhinus leucas)

A photo. blunt shark

Given that, technically, animals that live in the ocean cannot be in fresh water, this does not apply to blunt-nosed sharks, since they feel great in both sea (salt) and river (fresh) water. They have been found very far in the depths of the Amazon, almost 4,500 kilometers (2,800 miles) from the sea. This fish has special kidneys that can recognize differences in salinity and adapt accordingly. And you definitely do not want to meet such a fish in river water. They usually grow up to 3.1 meters in size, and these sharks have been reported to weigh 312 kilograms (690 pounds). Like many sharks, they have multiple rows of sharp, triangular teeth and extremely powerful jaws capable of closing with a force of 589 kilograms (1,300 pounds). It is also worth mentioning that this species of shark is especially unfriendly to humans, as they are among the top three sharks that most often attack humans (along with great white and tiger sharks). Also given their habit of swimming near densely populated areas, this has led many experts to call them .

4. Electric eels (lat. Electrophorus electricus)

In fact, the electric eel is much closer to catfish than to eels, but you probably don't want to be near one of them to find out. Reaching up to 2.5 meters (8 feet) in size, they are able to generate blasts of electricity from special cells called electrocytes located on their sides. These electrical discharges can reach up to 600 volts, this discharge is enough to make a horse buckle and fall. Although a single shock is not enough to kill a healthy average person, multiple shocks can cause the heart and lungs to collapse, and it is usually the shock that causes people to drown. That's why .

Most of the disappearances recorded in the Amazon have been attributed to eels, which put their victims into a state of shock and left them to drown in the river. Luckily for us, this type of eel tends to stick to a diet of amphibians, fish, small mammals and birds. They seek out their prey by emitting small 10-volt electrical discharges from their electrocytes, after which they stun or kill them.

3. Common piranhas (lat. Pygocentrus nattereri)

This is the real horror of the Amazon River, this animal is so feared that it has become the inspiration for many dubious Hollywood films. But in fact, the common (red-bellied) piranha feeds on carrion. But it is not at all worth understanding that they are not capable of attacking living beings; after all, it's worth considering that they can grow to over 30 centimeters (12 inches) in length and swim in large groups. Like all piranhas, red-bellied piranhas have incredibly sharp teeth lined up in a single row on each of their powerful lower and upper jaws. These teeth clench with great force, which is why they are the perfect weapon for tearing and eating flesh. Their fearsome reputation is largely fueled by rumors of their "feast madness" where a group of piranhas gather around an unlucky prey and gnaw them to the bone in a matter of minutes. Such attacks rarely occur and are usually the result of starvation or provocation.

2. Payars (vampire fish, lat. Hydrolycus armatus)

Anything called "vampire fish" is automatically associated with a scary animal, and payara is no exception. These fish are incredibly ferocious predators, capable of eating fish up to half their size. Given that they can reach up to 1.3 meters (four feet) in length, this is not at all worth understanding that this is the limit. They mostly like to eat piranhas, which may give you some idea of ​​just how tough these sharp-toothed beasts can be. They get their name from the two fangs that grow from the lower jaw and they are able to grow up to 14 centimeters (six inches) in length. Fish use them to literally impale their prey, and then viciously tear it to pieces. In fact, their fangs are so large that they have special holes in the upper jaw, designed to prevent their own piercing.

This voracious carnivore is fast and aggressive. They, as a rule, leave a small fish in their mouths, and then, skillfully maneuvering, begin to swallow. However, if the prey is too large, the payars may cut it into smaller pieces first and then swallow it.

1. Pacu (lat. Colossoma macropomum)

Certainly a far more dangerous animal for males than females, this is the pacu, which is larger than its closest relative, the piranha, and is known for its distinctive humanoid teeth. They look very similar to piranhas but have flatter, stronger teeth designed for crushing, and one fisherman reportedly died after having his testicles bitten off.

Fish expert Henrik Carl said the pacu is not usually dangerous to humans, but it does have a "pretty severe bite". He said: “There have been cases in other countries, such as Papau New Guinea, where some men's testicles have been bitten off. They bite because they are hungry, and testicles are just right for that. They usually eat nuts, fruits and fish, but human testicles are just a natural target."

Oh, and don't worry if you can't get to the Amazon to watch these monsters, they can already be found in Europe where they have already begun to breed.

In South America, spread over nine countries, is the Amazon rainforest, the largest rainforest in the world. It covers an area of ​​55 square kilometers and contains many types of biodiversity, including species that have not yet been fully explored. The Amazon River, which flows through the forest, supports a thriving animal and plant life. These forests are known as the "lungs of the Earth" because they absorb the most carbon dioxide on earth and release oxygen. These forests are also home to some of the most dangerous animals known to man. Here is our list of the 15 most dangerous animals in the Amazon rainforest.
This is the Alligator, found in the Amazon, which is one of the largest species in the world. This Amazonian tropical animal is a very skilled hunter and kills its prey by crawling up to it from under the water and then crushing it with its powerful jaws. He then drags the catch underwater until it suffocates. It kills all animals ranging from small fish, otters, dogs and deer to jaguars and other caimans. Caimans can grow up to 6 meters in length. The body of the black caiman is covered in hard scales that act as armor, however the color can vary between olive green, grey, brown or black. The species has bony ridges above the eyes. They have excellent hearing and vision and are equipped with strong teeth used for crushing food. You can also read about

This animal is not actually an eel, but a fish that looks like an eel. It has three organs that can generate five times more electricity than a conventional plug-in point. This makes it one of the . It uses this electricity to shock and immobilize its prey before eating them whole. It also releases electricity as a defense method to scare away an attacker. People are usually attacked by an eel if it is accidentally stepped on. Most deaths are not due to shock itself, but due to subsequent paralysis and drowning. This method of killing its prey has earned the eel a spot on this list of the ten most dangerous animals in the Amazon rainforest. The species has about 6,000 cells for producing electrocytes, and can generate 600 volts of power, which is about 5 times stronger than the electricity generated in a standard outlet. The shock is capable of instantly knocking a horse down. He is able to kill a person in two or three blows, but people very often come into contact with eels. The species can live 15 years in the wild and 22 years in captivity.

This large cat is native to South America and is the region's top predator. The jaguar lives alone in large areas, similar to leopards or tigers in India, and preys on small land animals. He rarely comes in contact with humans, and when he does, it's usually because he's trying to attack livestock. Though rarely attacked, this cat is a dangerous animal due to its speed, stealth, strong jaw and sharp teeth that can pierce even tortoise shells and human skulls. However, their numbers are declining due to habitat loss and hunting. It is also considered one of the strongest animals on planet Earth. Jaguars love to eat monkeys, crocodiles, deer, sloths, fish, frogs, and anything they can catch. Jaguars are solitary animals that like to live and hunt alone, however, this does not apply during mating season.

The red-bellied piranha, the most dangerous of all species, is a scavenger and usually eats dead animals. It has only been known to attack live animals if it feels threatened or if there is little food in the area. Humans have been attacked by piranhas, but these attacks do not result in death, only injury due to the sharp teeth of the fish. Piranhas are cannibalistic and have been known to eat other members of their species. It is also one of the deadliest fish in the world. Speaking of appearance, they have a silver body covered with red spots that serve as camouflage in murky waters. The pointed and sharp teeth of the piranha are arranged in one row and bite through a silver hook. The jawbone of the piranha is the strongest and is capable of crushing human hand in 5-10 seconds. Locals use piranha teeth to make weapons and other tools. Like sharks, piranhas are also equipped with a special organ that can sense blood in the water. They live up to 25 years in the wild and 10-20 years in captivity.

This animal of the Amazon rainforest is a brightly colored frog that secretes poison from glands on its skin. This poison is highly toxic and causes heart failure if ingested in large amounts. The golden poison dart frog is a rare species, but because it can kill twenty adults. It is known that some tribes in tropical forests The Amazons use the frog's venom to coat the tip of their arrows used to hunt other animals. Due to the depletion of tropical forests poisonous frogs are endangered and the blue poison dart frog is endangered due to its popularity in the animal market.

This shark is one of the three most dangerous species sharks and often attacks people who violate its territory. She lives in the muddy waters of the river and preys on other aquatic animals such as fish, dolphins, snakes. Since it swims in shallow, muddy water, people cannot see it, and if they get too close, the shark will attack them. A shark bite can be fatal because it pulls its victims into the water and they either drown or die due to blood loss. The species can grow up to 2.1 meters in length, however, females have been seen growing an average of 2.4 meters in length and weighing 130 kg. Males are smaller compared to females and weigh about 94 kg. They are one of the shark species that can grow in both salt and fresh water. The bull shark can switch between salt water and fresh water and vice versa. The bull shark will be able to survive even if the water level is only 60 cm, which is why they often come into contact with humans. Also, female bull sharks prefer to give birth in shallow water because this will prevent larger sharks from eating their young.

One of the largest snakes in the world, the green anaconda can grow up to 9 meters in length - twice the size of a giraffe. They live in the water and can silently sneak up on their prey and hit it with force, squeezing it with their powerful body until it suffocates and dies. They then swallow the prey whole. They usually prey on wild boars, deer, capybaras, and sometimes jaguars and humans. You can also read about the most. Anaconda non-venomous snake. They spend most of their time alone, however males seek females to mate between April and May. Sometimes several species of male green anacondas chase the same female. This phenomenon is known as "breeding balls" where dozens of males are wrapped around one female and they all try to mate. Sometimes green anacondas are engaged when female green anacondas eat smaller males.

This animal is not in vain on the list, because the spider has one of the deadliest poisons in the world. It is a ground spider that hunts at night. It can sting people who risk getting too close, and the venom causes severe pain and can eventually cause paralysis. The spider with the deadliest venom in the world is spread all over the jungle. However, during the daytime they hide under rocks and in crevices, in places that are dark and damp. Also, they are mostly seen where people have untouched items, clothes they don't wear, or piles of wood, or any items stored in a closet or garage, so people need to be careful. One of the most aggressive types of spiders will fight other spiders for territory if the population in that region is high.

As the name suggests, this centipede is a giant - it grows up to 30 centimeters. It is an experienced predator that kills small animals such as spiders, mice, small birds, bats, lizards and snakes. It is not venomous, but hunts by wrapping itself around its prey and eating it as it slowly dies. While it cannot kill humans, the bite causes intense pain, fever, and weakness. However, it is a ferocious and dangerous animal of the Amazon rainforest. This species has powerful jaws that can bite through the skin very easily and inject a very painful venom. Speaking of appearance, the whole body is divided into 23 parts, each with its own pair of legs. Amazonian giant centipedes do not breathe through their mouths, instead they have small holes in the side of each segment that allow them to take in oxygen to keep them alive. They are one of the fastest runners because they are almost blind and love to eat insects, tarantulas, small lizards, frogs, small birds, small snakes, rodents and even bats. The species is widely distributed throughout South America and several islands in the Caribbean. This is one of the .

This tiny ant - which grows to about 2 centimeters - gets its name from its ant, which is compared to a bullet. It also injects venom into the bite and can kill small animals. These ants hunt in groups and can paralyze or kill large animals with many bites. For humans, the bite is not fatal, but causes severe pain and can lead to temporary paralysis of the area around the bite. They have the most painful insect bites in the world and its bite contains a neurotoxin. It is located on the abdomen of the ant. They mainly nest in bushes, trees and in the ground.

This venomous species of viper has been mostly seen off the coast of the state of São Paulo, in Brazil. It can be recognized by the light yellowish brown color of its underside and the head shape characteristic of the genus Bothrops. The species can grow to a length of 70 cm, however it can also sometimes reach 118 cm. There are various combinations of colors, such as a pale buff ground color that is overlaid by a series of spots that can be triangular or quadrangular.

It is the most powerful predator found in the Amazon rainforest and also one of the largest existing species eagles in the world. This species is mainly found in the tropical lowland rainforests of Central America. Also in Brazil, the harpy eagle is also known as the royal hawk. The harpy eagle is national bird Panama and depicted on the coat of arms of Panama.

Bats - However, vampire bats have even more interesting feature, they are mammals that can only survive on blood. In addition, these species live in places of complete darkness, usually in caves, old wells, hollow trees, and buildings. Nocturnal creatures are most active during the early nights. The only bat species that can "adopt" another young bat if something happens to her mother.
