Piranha

Like the anaconda, the piranha is a well-known animal due to the film industry's infatuation with it. The most dangerous species, the red-bellied piranha, is a scavenger that typically consumes dead animals. It is believed to only attack living animals when threatened or when there is a lack of food around. Piranhas have attacked humans before, although these encounters only cause damage because of the fish's razor-sharp teeth. Piranhas are known to engage in cannibalism and consume other individuals of the same species. It is also among the world's deadliest fishes.

They have a silver body coated in crimson spots that functioned as camouflage in the murky waters, to speak of appearance. The species weighs about 7.7 pounds and can reach lengths of 5.5 to 17 inches. A silver hook will not withstand the bite of a piranha's single row of pointed, razor-sharp teeth. The jaw bone of a piranha is the strongest and strong enough to quickly crush a human hand. Piranha teeth are used locally to manufacture tools and weapons. Piranhas have a unique organ that allows them to detect blood in the water, just like sharks do. In the wild, they can live up to 25 years, and in captivity, 10 to 20 years.
