CrabThe crab is a type of crustacean similar to prawns, shrimp and lobster. There are more than 6,700 known species of crab found in waters worldwide and these many crab species are split into around 93 different crab groups.
Most crab species are found in the shallower ocean waters where the crabs tend to inhabit rocky pools and coral reefs. There are however, a number of species of freshwater crab that inhabit the waters in rivers and lakes and some species of tropical crab have been known to spend a great deal of time on land.
Generally crabs dont get bigger than 40 cm in size, with the exception of the Japanese spider crab that has been known to have a leg span of over 4 meters long! The smallest type crab is the pea crab with this tiny species of crab only growing to a few millimeters.
Crabs have a thick armoured shell which protects the crab from immediate danger. The crab also has two front armoured claws which the crab uses to catch its prey.
