ETYM AS. crabba; akin to Dutch krab, German krabbe, krebs, Icel. krabbi, Swed. krabba, Dan. krabbe, and perh. to Eng. cramp. Related to Crawfish.
Any decapod (ten-legged) crustacean of the division Brachyura, with a broad, rather round, upper body shell (carapace) and a small abdomen tucked beneath the body. Crabs are related to lobsters and crayfish. Mainly marine, some crabs live in fresh water or on land. They are alert carnivores and scavengers. They have a typical sideways walk, and strong pincers on the first pair of legs, the other four pairs being used for walking. Periodically, the outer shell is cast to allow for growth. The name “crab” is sometimes used for similar arthropods, such as the horseshoe crab, which is neither a true crab nor a crustacean.
There are many species of true crabs worldwide. The North American blue crab Callinectes sapidus, called the soft-shelled crab after molting, is about 15 cm/6 in wide. It is extensively fished along the Atlantic and Gulf coasts. Other true crabs include fiddler crabs (Uca), the males of which have one enlarged claw to wave at and attract females, and spider crabs, with small bodies and very long legs, including the Japanese spider crab Macrocheira kaemperi with a leg span of 3.4 m/11 ft. Hermit crabs (division Anomura) have a soft, spirally twisted abdomen and make their homes in empty shells of sea snails for protection.
Some tropical hermit crabs are found a considerable distance from the sea. The robber crab Birgus latro grows large enough to climb palm trees and feed on coconuts.

ETYM Old Eng. shrimp; -- probably so named from its shriveled appearance. Related to Shrimp.
Crustacean related to the prawn. It has a cylindrical, semitransparent body, with ten jointed legs. Some shrimps grow as large as 25 cm/10 in long.
The European common shrimp Crangon vulgaris is greenish, translucent, has its first pair of legs ending in pincers, possesses no rostrum (the beaklike structure which extends forward from the head in some crustaceans), and has comparatively shorter antennae than the prawn.
Small slender-bodied chiefly marine decapod crustaceans with a long tail and single pair of pincers; many species are edible. + prikaži više
