Many crustaceans are scavengers, feeding on scraps and dead creatures. Crabs, shrimp, and prawns search for food mainly at night and hide in crevices by day. Some crabs and lobsters are active predators, seizing prey in their powerful claws. Barnacles filter tiny creatures from the water using their hairy legs.
