Crustacean Meaning and Definition in Wikipedia

The Crustacea are a subphylum of arthropods with 50,000 described species. They are part of the phylum Arthropoda. Crustaceans include crabs, lobsters, crayfish, shrimp, krill and barnacles. They are relatives of insects. If the Arthropods are regarded as a superphylum, then the insects and crustaces would be phyla. (see List of animal phyla). The group has an extensive fossil record, reaching back to the Cambrian.

Most crustaceans are aquatic, mostly marine. Some have moved onto land permanently. Crustaceans that live on land include some crabs, and woodlice. Crustacea range in size from a parasite 0.1mm long, to the Japanese spider crab with a leg span of up to 14ft (4.3 m) and a mass of 44lb (20kg). The North Atlantic lobster can weigh more than 40 pounds.

Most crustaceans are mobile, but some become sessile after their larval stage. Barnacles become attached to rocks on thesea shore. Some are parasitic, like fish lice, and tongue worms. Crustacea usually have separate sexes, and the eggs hatch into larvae.
