Piranhas are tiny to medium-sized fish found in South American rivers. Some piranhas may be found in North American warm lakes and rivers, as well as in Bangladesh's Kaptai Lake. In Amazonian indigenous languages, the word piranha means "fish teeth." The exact number of piranha species is unclear (between 30 and 60). They aren't in any danger.
Facts about Piranhas that you Should Know:
Piranhas have a silver body with red spots that help them blend in with the muddy waterways they live in.
Piranha may grow to be 5.5-17 inches long and weigh 7.7 pounds.
Piranhas are said to have an insatiable hunger for blood, although they are really omnivores (eat animals and plants). Snails, fish, aquatic creatures and plants, seed, and fruit are among their favorite foods. When animals and birds fall into the water, which doesn't happen very frequently, they will feast on them.
Their teeth are sharp and pointed, and they have a single row of them. They may bite through a silver hook.
Their jaw bone is so powerful that it can crush a human hand in less than five seconds.
Piranha teeth are used to create weapons and other items by the locals.
Piranhas, like sharks, have unique sensory organs that allow them to smell blood in the water.
Piranhas are scavengers (eat their own species). When there are no alternative meat sources, they will attack and devour other piranhas.
Piranhas are portrayed in horror films as vicious man-eaters capable of devouring a human body in a matter of seconds. Piranhas, although living and feeding in huge numbers, need longer time to complete big prey.
The term "school" refers to a group of piranhas. There are 1000 fish in the school.
Piranhas' main predators include dolphins, crocodiles, and turtles.
Mating takes occur in April and May, when the weather is wet.
Females have the ability to deposit up to 5000 eggs.
Because both men and females look after eggs, 90 percent of them survive to hatch.
In the wild, they may live up to 25 years and 10-20 years in captivity.
