One of the classes of the arthropods, including lobsters and crabs; -- so called from the crustlike shell with which they are covered.
Subphylum which includes primarily aquatic arthropods with a hard exoskeleton and jointed appendages. Crustaceans are the only arthropods with two pairs of antennae. Animals in this phylum make up the most abundant part of the plankton community. Perhaps the most well known Chesapeake Bay crustacean is the Blue Crab.
class within the phylum Arthropoda noted for possessing biramus appendages and include such organisms as pill bugs, Daphnia, shrimp and crayfish
A large class of over 26,000 species of mostly aquatic arthropods having five pairs of head appendages, including laterally opposed jaw-like mandibles and two pairs of antennae.
class of mandibulate arthropods including: lobsters; crabs; shrimps; woodlice; barnacles; decapods; water fleas
A class of arthropods, which have gills and bodies covered by a hard shell (e.g. crabs, lobsters, shrimps).
a group of animals with two pairs of antennae and a calcium carbonate exoskeleton e.g. crab, lobster.
The group of arthropods including crabs, shrimps, lobster and barnacles.
Class of invertebrates to which the Atlantic blue crab belongs
a class of arthropods (jointed-legged animals) with hard 'crust' (=outer covering or skin), a segmented body, chitinous exoskeleton, and paired, jointed legs; distinguished from other arthropods by having two pairs of antennae
class of animal with hard crust or shell, segmented body, chitinous exoskeleton, and paired, jointed legs
Arthropods with a chitinous exoskeleton (ie, hard shell). These are the most abundant zooplankton, feeding on diatoms, copepods, fish eggs, larva, and other small organisms. Also includes the larger crayfish. From the Latin crusta, "shell or crust".
