Why is the Amazon River a forbidden zone for humans? Nine cruel creatures in the river, piranhas are the last

Why is the Amazon River forbidden to humans? How scary is it? So far, humans have not dared to develop this place. How many terrifying and brutal predators are hidden under its turbid river water?

Today, Brain Hole will share with you the nine cruel creatures in the Amazon River. All of them are extremely fierce. If a human falls into the water, it is estimated that they will not survive for half an hour . The old rules, I would like to ask you readers to use your little hands to make a fortune, give the author a free like and follow, thank you.

Well, number nine is Piranha. Piranha, also known as man-eating pomfret, has a body length of 30 cm. There are many species and are widely distributed in the Amazon basin. They are one of the fiercest predators in the Amazon and are often found in packs.

They are small in size but very violent in temperament, and their mouths are full of sharp fangs that can bite down a large piece of meat in one bite. A group of piranhas have allegedly been seen tearing a cow to shreds in just a few minutes . Although the credibility is not high enough, such rumors are enough to prove the horror of piranhas.

The prey they target will end up tragically. Because when piranhas hunt, they usually swarm up and bite. The blood of the prey is wounded, and the smell of blood in the water will make them more manic, with teeth as sharp as a surgeon's scalpel, frantically gnawing and cutting the prey until a pile of bones is left.

If we accidentally fall into the Amazon River, we can only pray that there are no piranhas around, otherwise, it is basically a near-death experience.

Ranked eighth, the human tooth fish. The piranha is a strange fish that lives in the Amazon River, also known as the Paku piranha, a close relative of the saw fat carp. This fish is not ferocious in temperament, but it is huge in size, up to one meter in length and 18 kilograms in weight .

Human toothfish has teeth very similar to humans, and this large white tooth is unique in the Amazon River. Although they have hard teeth, they are "vegetarian" and feed mainly on nuts dropped in water . Human toothfish eats like humans, using their teeth to crack open the shell of a nut and then devour the pulp.

How can a vegetarian fish become a cruel animal? This is because they like to attack the eggs of men. There have been reports of two men in foreign countries who died after being bitten by this strange fish. It remains a mystery as to why the fish like to attack the crotch of men.

Well, the seventh place, the giant water wolf fat carp with terrifying fangs, it is also called a giant big fang, a giant battle axe, etc., with two huge and sharp fangs in the lower jaw, about 7 or 8 cm in length , up to 15 cm long . This fish is sturdy and can grow up to 1.2 meters long, and has a large appetite. When preying, it can swallow half its own body weight of food.

When catching prey, the giant water wolf fat carp will penetrate the body of the prey with two fangs, and the method is very brutal. In fact, they are one of the most ferocious fish in the Amazon River . Even though the piranhas are usually intimidating, they seem to be very powerful. In front of the giant water wolf fat carp, they are a "brother".

Well, number six is ​​the giant otter. The giant otter, also called the Amazonian giant otter, is an aquatic carnivorous mammal native to South America, with a body length of 1.5 to 1.8 meters and a maximum length of 2.4 meters.

The giant otter and the African "flat-headed brother" are both mustelids, they look alike, and they have the same bad temper. In the Amazon basin, they are one of the natural enemies of piranhas.

The giant otter's forelimbs are very flexible and can hold the prey firmly. When hunting, the giant otter stabbed down with a shove, and when it came up, it had a piranha in its mouth, and then lay on the water, holding the small fish with both hands and began to nibble.

During the food season, an adult giant otter needs to eat 8 kilograms of fish a day , with recipes including piranhas, scavengers and even caiman. Yes, this unassuming little animal dares to wrestle with a crocodile.

Although the caiman is the natural enemy of the giant otter, it is limited to the water. Some smaller caimans are hunted by giant otters when they come ashore. Sometimes, the giant otter dares to go to the trouble of the jaguar, and has to sigh that there is really no one of the mustelids!

Well, fifth place, Arapaima. Arapaima is one of the largest freshwater fish in the world, reaching a length of 2 to 4 meters and a weight of 200 kilograms in adulthood.

Just by looking at the body shape, you know that they are not easy to mess with. The so-called "fish lives up to its name", Arapaima not only grows big, but also has a hard tongue in its mouth, as hard as a bone . Therefore, their way of preying is very simple. They open their mouths to suck small fish and shrimps into their mouths, and then use their bone-like tongues to crush the food with their mouths.

Small fish in the Amazon River, including piranhas, are its food. Moreover, their scales are so hard that they cannot be cut by ordinary kitchen knives. When the locals cook this fish, they use a hammer to knock the scales off .

Although the Arapaima is not ferocious in temperament, its own "hardware" is good enough, and it can easily stun an adult by flicking its tail.

However, the Arapaima have an impressively low IQ and are extremely curious. There is a little movement on the water, and they all come over to join in the fun. Therefore, the local people catch it very simply. They row a boat to make some noise on the river, wait for the fish to take the initiative to probe over and hit it with a stick, and it's over.

Well, fourth place is the bull shark. We all know that sharks generally live in salt water, and they are basically invisible in freshwater rivers.

But bull sharks can survive in fresh and salt water, and are the only sharks in the world that can enter and exit freshwater rivers . They can be found in the Amazon River. When the tide is rising, some bull sharks will swim into the river to find prey .

The arrival of the bull shark is a dimensional blow to the fish in the Amazon. Because the bull shark is a huge shark, it can reach 3.5 meters in length and weigh more than 600 kilograms.

Bull sharks are especially dangerous to people living in the Amazon basin. Just like their name, bull sharks are as strong as bulls and have a hot personality. They dare to attack even hippos, let alone humans. According to the International Shark Attack File, the bull shark has recorded 116 human attacks over the past few decades, second only to the great white and tiger sharks .

Well, number three, the electric eel. Electric eels are not strictly a type of eel, they are more closely related to catfish in terms of biological classification. But this does not affect the strength of electric eels. In the Amazon River, electric eels have no real predators. Almost all predators in the river dare not provoke it easily.

Because the electric eel is studded with discharge cells from head to tail, these cells act like "batteries" in series, and when stimulated by nerve signals, they release powerful electrical currents that instantly paralyze their prey . The electric eel is protected by a highly insulating structure on the outside of its body, and it will not electrocute itself when it is discharged in water.

Electric eels can release high voltages of up to 860 volts, knocking even strong crocodiles down. Locals have seen crocodiles attacking eels, causing them to twitch all over their bodies and keep their mouths open. The electric eel was bitten and unable to escape, and continued to discharge until it died.

In second place, the black caiman. The black caiman is the largest crocodile among the caiman and one of the largest extant land reptiles. They are 4.5 meters long and 500 kilograms in weight, and can grow up to 6 meters and weigh more than 800 kilograms. In the Amazon, few creatures are its opponents.

When an adult black caiman gets angry, it can easily topple a local canoe. Therefore, it is a very dangerous thing to encounter a black caiman while paddling a canoe.

Fortunately, black caimans are more "friendly" to humans and rarely attack humans. Sometimes, even if humans hold on to its paws, it will not get angry.

Well, number one is the parasitic catfish. Although the parasitic catfish are not considered ferocious predators in the Amazon River, they have to be the "ruthless characters" that frighten the locals the most. The parasitic catfish is very small, with a body length of less than 5 cm in adulthood, making it one of the smallest vertebrates in the world. But what does not match the appearance is the huge psychological shadow they leave on the locals .

As a parasitic fish, it swims very fast, burrowing into the gills of large fish to suck blood whenever it gets a chance. They have clusters of tiny barbs on their operculum, which can hook the host's flesh to fix the body.

Still, the tiny parasitic catfish are insignificant in the murky Amazon. If there is no special habit of attacking the human lower body, perhaps people will not care about it at all.

These small fish can cause the most excruciating pain. They are very sensitive to urine, and once humans enter the water, they attract parasitic catfish. Moreover, the parasitic catfish is translucent as a whole, and it is difficult to see with the naked eye in the water. When the locals are in the water, they are often attacked by them.

They will burrow into the urethra to suck blood and have been refusing to come out. Life is at risk if the fish is not removed surgically. That's why local residents believe that this small fish is the most terrifying animal in the Amazon.
