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

Excited for the August 21 eclipse? Visit our Eclipse 2017 page to explore the science, history, and myths of the event. The Curiosity team will be viewing the eclipse alongside NASA in Carbondale, Illinois. Follow us on Facebook for live videos, trivia, and interviews on the big day.

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.
