Underwater photography of the Amazon River

There are many kinds of creatures in nature, some are gentle and lovely, some are ugly and some are beautiful, but they are all cruel and bloodthirsty.

The piranha in the Amazon River is a wonderful complex. This dangerous species has strange and colorful colors and scales shining like phosphorescence, but at the same time it also has a row of sharp teeth, which can suck blood. It is ferocious, ferocious, creepy and discoloring. People who are afraid of its power call it "the Wolf clan in the water".

But such a fierce species is not the overlord of Amazon. Why?

Piranha's face

Piranha is actually smaller, as big as ordinary fish, and it is huge, like a discus, and it doesn't look very imposing. They are also like many animals, and the male body is more gorgeous than the female. Different piranhas may have scales of dark green, bright green, bright red and golden yellow ... as beautiful as underwater lights.

Among them, carnivorous and aggressive fish are generally gray, with dark green back and red scales in the abdomen. Although the scales are beautiful, the "faces" of these piranhas are not beautiful. Their eyes are flat, their jaws are strong, their jaws are prominent, their teeth are triangular and staggered up and down, and their faces look like an old man with sparse teeth. But they are not weak. The biting force of sharp teeth is amazing, they can even bite through steel plates, and even fishermen's hooks can sometimes bite through them.

Piranhas usually flock in search of prey. They have high IQ, are good at hunting, and are highly developed in hearing and smell. They can keenly sense the smell of blood in the water or the sound of prey. If animals or even people get into the water by mistake, groups of piranhas will swim to attack immediately.

They will not miss objects swimming in the water, and even dare to attack large prey dozens of times their own bodies, quickly and accurately attacking weaknesses such as animals' eyes or shoulders, making their prey lose the ability to escape and resist. They swarmed, biting their prey tightly with biting teeth, twisting their bodies desperately to tear the meat of their prey alive, and their teeth quickly exchanged to devour their prey, and some even directly bit down 16 cubic centimeter of meat.

In this way, sharp teeth cut pieces of meat like blades, and the smell of blood will only make them more excited. In a blink of an eye, all the living animals were eaten up, leaving only a pair of bones in the water. Anyone who witnessed piranha hunting was shocked.

The fierce name is out there.

Because gregarious piranhas are very lethal, even giant and fierce crocodiles will feel scared when they meet a group of piranhas, and immediately turn over, with their backs facing the sky and their backs facing down, so that piranhas can't chew their stomachs and avoid being bitten to death.

Piranhas also know how to hide in the dark and wait for an opportunity to go out. When the waters shrink in the dry season, they will also lurk and kill their prey as they pass by. Sometimes, cows and people walking by the water's edge, if they slip, will instantly become their delicious meal. Piranha became notorious and became a famous "killer".

Even if you get away with it, your deep bones and bleeding wounds are enough to leave a lifelong shadow.

On Christmas Day 20 13, many people who could not bear the heat jumped into parana river, hoping to have a cool summer. As a result, it attracted a large group of piranhas. Swarms of piranhas passed through the crowd, as if starting a bloody banquet. Everyone hurried to the shore and was taken to the hospital. In the end, dozens of people were killed, including many children, and a girl's finger was bitten off by a piranha.

Others fished in the water, and as a result, piranhas were bitten off the flesh of their palms. Even a pond dedicated to feeding mermaids can hurt people. Although there are not many cases of large-scale wounding, it is worthy of vigilance. Piranhas are like evil spirits in deep water, flashing, and appearing represents blood and fear. Many film and television works also directly use the appearance of piranha as an index to tell some thrilling suspense stories.

But it sounds like piranhas are fierce and can dominate the Amazon River. But even the fiercest creatures have natural enemies and weaknesses, and the weakness of piranhas makes them unable to become the overlord of the Amazon killing list.

It is difficult to become a hegemon

Piranhas can eat animals that stray into the water, but they won't wait for them. They usually eat other fish in the water. Their discus-like bodies also prevent them from swimming to a certain extent, and piranha's eyes are not very good. The Amazon River is turbid, and the visibility is not high. Piranhas can't catch too many prey only by smell and hearing.

In addition, some fish also have ways to protect themselves from being swallowed, such as civet catfish, which can fight the fangs of piranhas. Catfish swim much faster than piranhas. Even if caught by misfortune, they can immediately spread the thorns on their backs, leaving piranhas with nowhere to eat. At least in catfish, piranhas can't help it.

Moreover, piranha is also a member of the food chain, and it is not indestructible. Electric eels can eat it. When hunting, the electric eel will send out high-voltage current and corona dozens of piranhas together. Even if their teeth react quickly, they can't escape this "power grid" and can only be eaten completely.

Not only that, piranha also has a fatal disadvantage. That is, although he is good at killing prey in groups, piranhas who fight alone are not so powerful. As I said before, piranhas are small in size, and they mainly hunt by biting in groups. Once they leave the group or are raised alone for a long time, they will become timid and weak when they meet their prey.

Some people even like the ferocity and wildness of piranhas, and will raise individual piranhas and then show their fingers in front of guests. This is certainly dangerous, but it also succeeded, at least proving that piranha is not so cruel.

And not all piranhas eat meat, and some subspecies only eat fruit and carrion. Piranhas that kill people outside are only part of it. There are also some piranhas with good taste, chewiness, tender belly and nutritious skin, which also kills its fierce name to some extent.

summary

Piranha is feared by everyone because of its fierce appearance and the characteristics of being in groups and killing quickly. But in fact, sometimes their fierce names are exaggerated. Many piranhas are edible, and only some of them are really fierce.

Moreover, a single piranha has little power after all, and there are many natural enemies to deal with them. Piranhas can't dominate the Amazon river after all.
