What are the natural predators of piranhas? Are piranhas the most powerful fish?

There are natural predators.

The natural predators of piranhas include waterbirds, caimans, giant otters, freshwater dolphins, etc.

Natural enemies refer to a certain animal in nature that specializes in preying on or harming another animal, and these kinds of animals will prey on piranhas, so several are natural enemies of piranhas. Piranha, also known as piranha, is a fish distributed in the Amazon River in South America, a species of piranha, there are nearly 56 species of piranha, belonging to the subfamily of sawfish in the family Lipid Carp.

Do you know what the natural enemies of piranhas are? Today I finally understood, it turned out to be inconspicuous!

In order to deal with piranhas, there are many fish that have developed their own in the competition for survival for thousands of years"Tip**"。For example, the high-voltage current emitted by a single electric eel can send more than 30 piranhas"Electric chairs"Punish with death, and then slowly eat it again.

The spiny catfish is good at using its sharp spines, and once it is targeted by a piranha, it swims as fast as possible to the belly of the bottom piranha, and no matter how the piranha swims, it moves in sync with it. If the piranha wants to bite it, the spiny catfish immediately spines angrily, making the piranha helpless. And on the Amazon River killer list, the catfish is ranked first, and the piranha is only ranked fourth.

Piranhas also have a unique nature, and it is only when it is in a group that it is incomparable. Some fish lovers raise them in glass tanks.

A piranha, in order to show his bravery in front of guests, sometimes he deliberately puts his hand in the water, and in most cases he is unharmed. If you have a finger injury, it's a different story.

If a guest approaches the glass jar or the host makes a sudden gesture, this is true"The horror of the Amazon"The so-called piranha was so frightened that it retreated to the farthest corner of the fish tank and did not dare to move. Obviously, piranhas, which are usually invincible when they are in groups, once they leave the group, they become poor cowards.

Thank you.

The natural predator of piranhas is the arapaima. In the Amazon basin, piranhas are a group of terrifying predators, rushing up to their prey and gnawing their prey to the bones in an instant with their sharp teeth. But arapaima is known as the natural enemy of piranhas, arapaima scales are large and hard, inlayed, can well defend against piranha attacks, at the same time arapaima is very powerful, using the tail as **, brute force is very strong, enough to stun piranhas.

Piranha living environmentPiranhas inhabit the main stream, large tributaries, wide rivers, and strong currents. Adults feed mainly at dawn and dusk, mainly insects, worms, and fish, but some of their similar species only eat fruits and seeds. The activities are mainly during the day, and at noon, they will rest in a sheltered area.

The water quality requirements are not strict, and it prefers weakly acidic soft water, and the suitable water temperature for growth is 22 to 28 degrees Celsius. This kind of fish forages in groups, staple feeding on relatively small individual fish, preying on anything that moves in the water, and is especially sensitive to the smell of blood, any slightest smell of blood will provoke a large school of piranhas to attack furiously.

No, what's at stake, all things are mutually reinforcing, and every animal has its own biological existence.

Not necessarily, sharks are pretty powerful.

Probably, because piranhas just eat human flesh.

The natural predator of piranhas is the giant otter. The giant otter that lives in the same river as the piranha is the largest species of all otters, the otter is called "the flathead brother in the water", and the giant otter is the largest otter in the otter, which shows how aggressive it is, the giant otter is also considered one of the top carnivores in South America, the otter feeds on fish, and in its eyes the piranha is fierce, it is a fish, all in its diet.

The power of the giant otter:The piranha is very ferocious, but because of its clumsy size, the discus-shaped body shape causes the piranha to swim fast enough, and the swimming speed is relatively slow, while the giant otter has super swimming ability and excellent hunting skills, even the crocodile does not dare to provoke the giant otter easily, and the slow swimming piranha naturally cannot escape the pursuit of the giant otter.

Due to the slow swimming speed of piranhas, which is good for many fish, and the visibility of the Amazon rivers is usually no more than 1 meter, and the distance between the piranhas and the prey when attacking cannot be more than 25 centimeters, they rely more on the smell of blood, giving other fish more time to escape.

One of the natural predators of piranhas is the electric eel.

Electric eels often hunt at night, and their diet includes small fish, crabs, shrimp, crustaceans, and aquatic insects, as well as rotting carcasses of animals, and some individuals have higher plant detritus found in their food. When the electric eel hunts, it first quietly swims close to the fish, and then it can continuously release electric current, and the fish that have been shocked immediately faint and stiffen, so the electric eel takes the opportunity to devour them. The feeding intensity and growth rate of electric eels increased with the increase of water temperature, and were generally the highest in spring and summer.

Electric eel discharge, sometimes not necessarily for predation, can also be a physiological need. Fish that are electrocuted by electric eels often exceed the amount they need to eat, which is a hazard to fishery production. Eel.

Thorny catfish.

The spiny catfish is good at using its sharp spines, once it is targeted by the piranha, it will swim to the bottom of the belly of the piranha as fast as possible, no matter how the piranha swims, it will synchronize with it, as long as the piranha wants to bite it, the spiny catfish will stab them to death with the spines on its body.

Piranhas mostly grow in the turbid waters of the Amazon, and they are very adaptable, and can survive in weakly acidic to neutral water, and the water temperature is best controlled above 20, and it is best to keep it above 24-26.

Piranha habits

The piranha pomfret has red eyes, an oval body, a flattened side, and a caudal fin that is also shaped. The body is grayish-green, the back is dark green, and the abdomen is bright red. With sharp teeth and well-developed jaws, it is known for its ferocity.

Distinguishing between males and females is more difficult. Generally, males are more colorful and smaller, while females are larger and lighter in color, and their abdomen is more distended when they are sexually mature.

Mature piranhas are similar in appearance to males and females, with bright green backs and bright red bellies with markings on the sides. Have a highly developed sense of hearing. The two jaws are short and powerful, the lower jaw is prominent, and the teeth are triangular, sharp, and staggered up and down.

After biting the prey, he clenched and tore the meat off with the twisting of his body, and he could bite down 16 cubic centimeters of meat in one bite. The alternating replacement of teeth allows for continuous feeding, and strong dentition can lead to severe bites.

Piranhas have many predators in nature, including egrets, cormorants, herons, electric eels, crocodiles, otters, freshwater dolphins, large catfish, and humans.

It is mainly found in rivers east of the Andes to the Brazilian plains. In addition to the Amazon, the Cuyaba and Olinoco rivers are also its main sources. It is now located in the Amazon River basin of South America, distributed in Argentina and Brazil.

Reproduction:

During the breeding season, more than 1,000 broodstock lay their eggs on tree roots in the water. 9 10 days of incubation, broodstock will protect the eggs. Flooding of rivers can affect the success rate of hatching.

It is quite difficult to breed in aquariums, which is why they are so expensive, and not as cheap as redfin pomfrets. They are sexually mature at 18 months, and males tend to be a little more vibrant.

During the breeding period, the eggs are laid on the roots of trees in the water, and the eggs are sticky. It can lay thousands of eggs at a time. Broodstock will protect their eggs, and the fertilized eggs hatch after 9 to 10 days. The flooding of the river can affect the success of its reproduction.

Piranhas have many predators in nature, including:

egrets, cormorants, herons. There are also crocodiles (caimans), otters, freshwater dolphins, large catfish, as well as mutual cannibalism, disease, and so on.

Plus every year locally"Natives"Mass capture and drought.

As a result, piranhas have not decreased in nature, and even some species have become very rare.

Some experts point out that it is believed that one day, piranhas will disappear into nature.
