n A member of the class Crustacea in the phylum Arthropada Includes shirps, lobsters, crabs and water fleas Most forms are aquatic, although a few are terrestrial, living in damp places
A crustacean is an animal with a hard shell and several pairs of legs, which usually lives in water. Crabs, lobsters, and shrimps are crustaceans. an animal such as a lobster or a crab that has a hard outer shell and several pairs of legs, and usually lives in water (crustaceus, from crusta; CRUST). Any member of the 45,000 arthropod species in the subphylum Crustacea. Distributed worldwide, crustaceans are distinguished by having two pairs of antenna-like appendages in front of the mouth and other paired appendages near the mouth that act like jaws. Most species are marine, including shrimps and barnacles. Some, including crayfishes, live in freshwater habitats; others (e.g., sand fleas, land crabs, and sow bugs) live in moist terrestrial environments. The typical adult body is composed of a series of segments (somites) either fused or linked to each other by flexible areas that form movable joints. The carapace (shell) varies in thickness among species and must be periodically molted to allow growth. Many species of marine crustaceans are scavengers, and many (including copepods and krill) are significant components of the diets of larger organisms. See also decapod
Animals that wear a segmented shell and have segmented legs are arthropods, such as insects and crustaceans Crustaceans are arthropods that live in the water and breathe by gills, such as lobsters, barnacles, crabs, and shrimps
A group of freshwater and saltwater animals having no backbone, with jointed legs and a hard shell made of chitin Includes shrimp, crabs, lobsters, and crayfish
An arthropod with five pairs of appendages on the head (including two pairs of antennae for sensing of the environment, a pair of mandibles for manipulating food, and two pairs maxillae for feeding), and separate thoracic and abdominal areas (often with visible segments in each) with appendages attached to each body segment (including decapods, copepods, amphipods, and many other forms)
