Piranhas, known as "werewolves in the water", are mainly distributed in the Amazon rivers, and the piranha is one of the most notorious animals because of its sharp teeth and herds of attacking large animals.
In Brazil, a group of water goby fish has witnessed the horrific sight of a cow torn to pieces in just a few seconds, though not realistic enough. The goby has distinctive triangular teeth and is incredibly powerful enough to tear its prey apart. When they eat, they eat their prey cleanly, leaving only a pile of white bones.
