Piranha
It is revealed that sharks are notorious as "man-eaters". They sometimes bite swimmers in the water very quickly or crew members trapped in the sea due to shipwrecks. However, no matter how miserable it is, it cannot compare to South America. A small fish in the inland river - piranha.
Piranha is commonly known as piranha. Its head accounts for a large proportion of its body, and it has thick bones that tilt backward. The big round eyes are occasionally blood red, and the mouth is full of triangular tines, as sharp as razors. No matter what river animal you encounter, you only need to bite it, and you will bite off a neat piece of meat, which is as big as a coin with a diameter of 2 and a half centimeters.
Piranhas often hunt for food in groups, and occasionally there are hundreds of them in a group, and their killing speed is particularly alarming. In February 1996, a Volkswagen rolled down the Heilub River from a ferry 200 kilometers east of Manaus, where piranhas are often found. Nine hours later, rescue workers arrived at the scene and found that most of the 38 passengers who died in the accident had only bones left under the sharp teeth of the piranha.
Even though this situation often occurs, many experts believe that the common rumors about the harm of piranhas to humans are exaggerated.
It may not be just one factor that urges piranhas to attack other animals, but a combination of several factors, including hunger, low water levels and too many species concentrated in one area. The piranha has sharp eyesight and can use its vision, senses and sensitivity to water wave vibrations to find food. When it smells the smell of blood, it will go crazy, open its mouth, and strike at the source of the blood smell like a sword, very fast. , what the human eye can see is just a fleeting hazy black shadow.
Piranhas have the courage to attack animals several times larger than themselves. If the piranha preys on a big fish, it will bite off the tail of the big fish first, making it unable to move. When it was time to eat, each piranha took a bite of the big fish, pulled it back hard, and tore off the fish meat, leaving a gap for the other piranhas to eat. They moved at an unbelievable speed and in the blink of an eye. Then he ate the food he caught. When the piranhas are unbearably hungry, even birds cannot remain safe. Herons, egrets and wild ducks flying close to the water will occasionally disappear suddenly into the spray and blood.
However, the piranha also suffered retribution: the Indians discovered that its meat was delicious, so they often crushed a kind of poison ivy bark and sprinkled it on the water to poison it. They caught dozens of them at a time and put them in the hot pot. coalApply roasting and moxibustion to bring good luck
When piranha hurts people, it is usually an accident, or it may be due to the person's own fault. Take, for example, what happened to an Indian chief on the upper reaches of the Tabazos River. The chief killed a chicken and took it to the lake to clean it. He probably threw the chicken's internal organs into the lake. Later, he put his hands into the water and shook them back and forth, trying to wash away the blood marks on his hands. Suddenly something rushed under the water, and then he yelled and retracted his hands - one index finger was neatly bitten off. A person who witnessed this incident said: "The local villagers were very thoughtful and thought that the chief himself should be blamed for not putting his hand into the water, rather than the piranha biting off his finger."
