Decapoda is an order of crustaceans in the class Malacostraca. Many familiar groups, such as crayfish, crabs, lobsters, prawns and shrimp are in this order. Many decapods are scavengers - they eat dead plants and animals. Crabs are mixed feeders, taking algae and shellfish such as molluscs. Lobsters eat mostly live prey.
