Isopod (Arcturus baffini)

Isopods form a very diverse group of Crustaceans. Arctic marine isopods such as this one are mostly carnivorous and feed on dead whales, fish, and squid; they may also be active predators of slow-moving prey such as sea cucumbers, sponges, radiolarians, nematodes and other zoobenthos. These invertebrate animals are related to the terrestrial sowbug, which can often be seen in basements or gardens. The species shown here is a suspension feeder, meaning it feeds on particles of food floating by in the water.
