Piranhas (15 photos)
I caught the eye is such information: Black piranha - the most severely-biting creature on Earth. The researchers calculated that her jaw muscles attach to allow the bite force of the equivalent weight of 30 individuals of the 20-centimeter fish. Such talents no one other living creature we know of in the world.
Great white shark, crocodile or a hyena bite pretty impressive too, but if you compare them to the bite force in relation to the overall size and weight, black piranhas will leave them far behind: this characteristic fish surpass even the prehistoric monsters, such as Tyrannosaurus and ancient kit- "zhevatel».
Let's learn more about these fishes ...
The word "piranha" has its roots in the Tupi Indian language, it comes from the word "feast" (fish) and "Rana" (Saw). (according to another version the word "piranha" borrowed from South American Indians and means "toothy demon».
). And knowing a little about the habits of the fish, unwittingly agrees that his name she received deserved.
Piranha - the fish from the family of tetras that predlezhit toothcarps squad. In the natural environment inhabited by piranhas in many freshwaters of South America. Undoubtedly, the most famous piranha habitat - the Amazon River.
Piranhas "glorified" their extremely aggressive character, although the first thrown them look the person usually does not realize that before him the most dangerous predator. The body of the piranha high, laterally compressed, body color ranges from silvery-blue with dark spots to dark gray with sequins. Young piranha tip of the tail and the place where the body goes into a tail fringed with dark stripe. The average length of adults is 30 centimeters.
Piranhas are armed with razor-sharp, teeth plate. Piranha teeth are arranged so that when compressed between the jaws is not the slightest clearance. Piranha jaw so powerful that one bite of the adult easy snack stick as thick as a human finger.
Today piranhas often found in aquariums lovers. It is noteworthy that in the aquarium of piranhas lose their aggressiveness, but do not lose their fearsome appearance that they give low-set eyes and a high forehead. The well-fed aquarium with piranhas can safely drop the hand. But in some case, it is not necessary to do this if you have a hand in the drawn-cut or not even a drop of blood. The aquarium piranhas like to sit in the dark shelters. Piranhas get along quite well in a tank with other members of the squad tetras.
Surprisingly, piranhas, being one of the most dangerous predators at the same time extremely shy! The aquarium, which will live piranhas, it is advisable to keep away from sources of noise and shadow, or your pets will always be on the verge of fainting! Well-known among aquarists is the fact that quite clicks on glass or sharp movements around the aquarium to piranhas fainted. Also, they often pass out during transport from the place of purchase for future housing.
It is interesting to observe the moment of feeding piranhas in the aquarium. Calm and graceful fish (yes, you heard right!) Instantly turn into hungry predators and eagerly attacked the food. And what a pleasure to watch as piranhas leap out of the water to grab a piece of goodies thrown you! When feeding piranhas important not to forget that they eat as much as they need and, in contrast to the labyrinth fish, do not examine the bottom of the presence of food has fallen.
Piranhas - a fish that have fall in love with yourself. It is enough to admire these fish a few minutes that you have a desire to have them in your aquarium!
Shepherd the flock is distilled through a river, where there are piranhas have to give one of the animals. And while the predator victimized victim away from this place the whole herd is transported safely to the other side Wild animals were no less intelligent than men. To get a drink of water or to cross the river, where there are piranhas, they begin to attract the attention of predators noise or splashing water. And when a bunch of piranhas rush of noise, animals are moving along the shore to a safe place, where they drink quickly or cross the river.
Quarrelsome character piranhas often causes them to quarrel and attack each other. But some amateur aquarists, in spite of everything, run the risk of keeping these fish home.
Piranhas attack every living creature was within their reach: the large fish in the river are domestic and wild animals, man. Alligator - and he tries to get out of their way.
Ironically, piranhas - caring parents and stripped of all their homes.
The family includes several species of piranha carnivorous and herbivorous large number of species. The most common - a common or, as it is called, red piranha. It is widespread in fresh waters of South America, is almost universally found in the Amazon, Orinoco, and La Plata. It can also be found in the eastern foothills of the Andes and Colombia around the Amazon basin in Bolivia, Paraguay, Peru, Uruguay and the northeast of Argentina. Minor populations of piranhas are also available in the United States and Mexico, in Europe, in Spain and other countries, where they were from amateur aquariums.
Some countries have tried to completely destroy the piranhas. In Brazil, they tried to poison her poisons, but piranhas are very hardy. As a result, piranhas remained unharmed, and other inhabitants of the affected waters. But you can not destroy the piranhas also because they need nature. Piranhas, like wolves, are nurses - kill weaker, old and sick. Thereby, they make their victims populations stronger. And if you do not want to suffer from the piranhas, just do not climb into the water, if you know what they are found.
Scientists from the United States, Egypt and Brazil for the first time measured the bite force redeye piranha (Serrasalmus rhombeus). It is the largest representative of modern subfamily piranha. Adult fish reach a length of 40 centimeters and weigh more than a kilogram.
As reported in an article published in the journal Scientific Reports, researchers have caught 15 fish in the Amazon in length from 20 to 37 centimeters and, at the risk of your fingers, teased them dynamometer. Piranhas willingly participated in the experiment and actively biting the proposed instrument.
The results showed that the most powerful bite force was 320 newtons. Recall that for odinnyuton accepted the force required to move the body mass of one kilogram one meter per second.
On the Earth's surface on the body weight of 1 kilogram of the force of gravity, which is equal to 10 Newton. Thus, the jaws of fish under pressure 30 times its weight. This result makes the absolute champion piranha bite force relative to body weight as among the modern inhabitants of the planet, and among extinct predators.
Scientists compared the skeletal structure of modern piranhas and their ancestor's largest Megapiranha paranensis. Calculations have shown that the strength of the bite of the fish, which reaches a length of 1, 3 meters and a weight of 72 kilos, reached 4840 newtons, which is equivalent to 480 kilograms.
Previous studies have shown that the giant Tyrannosaurus rex jaw clenching just three times stronger despite the fact that the weight of one of the largest predators of the Cretaceous period up to ten tons.
If we add to the powerful jaws of fossil piranha teeth with thick roots and a serrated blade, like a hunting knife, an image emerges is not a harmless creature. Researchers believe that with this set of prehistoric predator could crush the shells of turtles and bite through the scaly armor ancient soms.
