A Predator? An Alien? A re-shaped Piranha?
This Predator resembling creature is a Giant Isopod and is one of the Ugly Animals. Its scientific name is "Bathynomus giganteus" (Who cares? :)). It is a carnivorous (flesh-eating) crustacean (Being or having or resembling a hard crust or shell). This Ugly Animal passes its time cleaning the deep ocean floor, up to 6,000 feet down on the sea floor where literally is no light at all. This lives by eating the dead, decayed fishes and other marine animals.
