More About Crabs ...
|
Crabs are various species of decapods. They are crustaceans with five pairs of legs, the first pair modified to form a pair of pincers, a flattish shell, and a short, broad abdomen folded under its thorax. There are two main groups of crabs: the Brachyura or true crabs, and the Paguroidea, or hermit crabs. Crabs are related to lobsters and shrimps.
Groups of crabs include:
Blue crab Dungeness crab Coconut crab Fiddler crab Ghost crab Hermit crab Japanese spider crab (largest crab alive) Jonah crab Lady crab, Calico crab Mangrove crab Mole crab Mud crab, Black fingered mud crab, White-tipped mud crab Oyster crab Rock crab Pea crab Purse crab Spider crab Stone crab A number of animals with a similar shape are commonly called crabs, including the crab louse (an insect), the Horseshoe crab (in the class Merostomata).
