There are more than 20 kinds of piranhas. Which piranha is the fiercest?

Piranha, commonly known as piranha and piranha, is a carnivorous freshwater fish in South America. They are usually 15-25 cm long, and the longest can reach 40 cm. Piranhas have sharp teeth (they can easily bite off steel hooks or human fingers) and are very fierce. Once they find their prey, they usually attack it in groups. Piranha can eat a rib head of a live cow in 10 minutes. The local people use their teeth as tools and weapons. Rivers such as Amazon, Guyana and Paraguay are frequented by piranhas. Piranha is also used to describe cruel and inhuman people. There is a novel of the same name.

I don't know if it's like this:

Black violet piranha (Serrasalmus? Rhombeus), commonly known as black piranha, English name: White? Piranha? Black? Piranha? Cerasa Moss. The Niger River is distributed in the Amazon basin of South America, with a maximum length of about 50 cm.

This fish comes from the Burxue tribe in the Amazon basin. Buer snowman is good at swimming, mainly catching creatures in Heihe area.

Generally speaking, primitive tribes worship gods with male and female genitals or land animals such as eagles, leopards, tigers and snakes. They supply this kind of black violet piranha that grows in the Amazon river basin, and there is a custom of offering sacrifices to the living.

The appearance of this ethnic group is the same as that of people from nearby tribes, but it is short in size, with long toes and webbed skin. The characteristic of this nation is that it likes to tattoo its body like scales.

Although there are piranhas in the living area, Buer snowman is rarely disturbed by black piranhas when fishing. It is said that this is God's blessing. Babies in this family will add the excrement of black piranha to their children's diet until they are about seven years old. The excrement was collected from a circular cave in the shallows. After laboratory tests, it was found that in addition to vitamins rich in minerals, there were biological factors and animal hormones.

There are many myths and legends about piranha and Heihe River, which makes rivers and fish gods more mysterious.

However, the eyes of the black violet piranha are not red. Look at the first picture. ....
