Total number of species: 7000

With over 6500 different species, crabs are one of the most varied aquatic dwellers in the world. These crustaceans have a thick exoskeleton to protect their inner organs with an oblong, square, or diamond-shaped central body cavity, four sets of legs, and one pair of pinchers. Crabs range in size from the tiny pea crab measuring only 10-15 mm (0.4-06 inches) to the giant Japanese spider crab, which can grow up to 4 meters (13 feet) across.
