Giant Isopods, The Ocean's Super-Sized Roly Polies

Like their terrestrial pill bug cousins, giant isopods are crustaceans. However, unlike roly polies, they live in the deep sea and can grow to be the size of a cat. They're often seen feasting on the remains of dead animals that have settled on the ocean floor.
