Giant isopods are big crustaceans that live at the bottom of the ocean. They can grow up to 45 cm long and weigh up to 1.7 kg. Currently about 9 different species are known. Giant isopods usually eat dead whales, fish and squid. They may also be active scavengers, and hunt slow-moving prey, such as sea cucumbers, sponges, nematodes. Perhaps they even catch live fish. They live in depths between 170m to about 2200m. Over 80% can be found between 365 m and 730 m of depth. They probably prefer a muddy or clay substrate and lead solitary lives.
