The Amazon River is one of the regions with the most aquatic life in the world. Piranhas, anacondas, caiman crocodiles, etc. are the most horrible species in this region. At the same time, more species are gathered in the whole area covered by the Amazon River, including 2.5 million species of insects, tens of thousands of plants and about 2, species of birds and mammals. According to the assessment of scientific experts, there are more than 75, kinds of trees and 15, kinds of higher plants, including 9, tons of plant biomass, per square kilometer in the Amazon region.

So the Amazon River is regarded as the life kingdom on the earth, with many biodiversity and complex biological populations. Basically, no one dares to set foot in this primitive ecological area alone. Let's take a look. What is the scariest animal in the Amazon River? We have also mentioned several kinds above, so let's briefly introduce how horrible and terrible this river, which is called the second longest river in the world and has the largest flow in the world, is, and the creatures may be enough to make people feel horrible and terrible.

First, piranha

Piranha is a kind of piranha. There are nearly 56 species of piranha, and we often call it piranha, freshwater pomfret and Bila fish. This kind of fish looks terrible, and at first many experts thought that piranha was not so terrible, but in 1981, an accident of Obidos capsized the experts forever, that is, this kind of fish was really terrible. When people fell into the water, they flocked to the crowd and attacked, so 3 people died in their mouths in this accident of Obidos capsized.

So piranhas really want to attack people. They have very sharp teeth. Some people have witnessed the terrible scene that a group of piranhas tore a cow to pieces in just a few seconds. Although the authenticity is not high enough, the biting power of piranhas is very amazing. It is easy to completely tear their prey and eat it in their own mouths. Any prey they attack will eventually leave a pile of bones, so piranhas are the most amazing in Amazon.

Second, anacondas

Among the shallow rivers in the Amazon, anacondas are the largest existing snakes. Adult anacondas are 5-1 meters long and weigh up to 22 kilograms. Most of the time, they are hidden in the water, and basically only their nostrils are exposed to the water, so it is difficult to detect that they will only be exposed to the water when they meet their prey. However, anacondas mainly prey on terrestrial animals, such as mammals and birds, and also eat alligators in some places, so they are basically hidden in the water.

Anaconda is an expert swimmer, and has almost no natural enemies. At the same time, such a giant creature is always frightened when people see it. However, anacondas generally do not attack fishermen, so there have been no records of cannibalism in the world in the past 1 years, but more than 6 tons of anacondas have been slaughtered every year. Of course, most people have a sense of terror when they see it, and it is not ordinary people who can destroy anaconda. This is a special situation. Humans have become natural enemies of anacondas under different circumstances, of course, most of them are based on interest chains.

Third, the black caiman

The black caiman is the largest kind of caiman. It can reach 4.5 meters in length and 453 kilograms in weight. This creature is also a "master swimmer" in the Amazon River. It also has a very powerful skill, that is, the black caiman can change from a crawling state to a "walking" state just like people, which completely peaks itself.

So this is also a very frightening creature. At the same time, although these habits are intimidating, the black caiman rarely attacks humans, and has a friendly relationship with people. However, it is not absolute that it will not attack people. When people get too close to their nests, they will also be alert and attack. Once the black caiman attacks human beings, there is no strength to fight back, and the result is extremely tragic, so human beings are both happy and afraid of the black caiman.

On the whole, we said that this is a horrible species, among which piranha should be the scariest, and it attacks people or other prey in groups. As long as the prey is caught, the result is very miserable, that is, bones are left, while anacondas and black caiman are scary-looking species, but as long as humans don't influence them as much as possible, they won't take the initiative to attack people, so it's relatively better. These are the three scary species we are talking about. Of course, there are some scary creatures, such as green python, giant bone tongue fish and giant otter, which have a great impact on human beings. This is the general situation.

So the ecological environment of the Amazon River is very good, but no one dares to swim in the river at all. Even people in this area are very scarce, because no one dares to live here and swim. These creatures may have a fatal crisis at any time. This is the terrible thing about the Amazon River. The above three kinds of creatures are enough to make you tremble. It is also said that swimming survives, even if you see it, you will run away.
