Description Crabs belong to the order Decapoda and they can be can be classified into two main groups,
brachyuran crabs (infraorder Brachyura) and anomuran crabs (infraorder Anomura). Most species
of Brachyura, or true crabs, can easily be separated from the so-called “false crabs” belonging to
the infraorder Anomura by having five pairs of locomotory appendages of a crab (the pereiopods)
are made up of a pair of usually powerful chelipeds (legs carrying a chela or pincer) and normally of
four pairs of walking (or ambulatory) legs. The first appendage is referred to as the cheliped and the
last four appendages (walking legs) as legs. The claw (or chela) itself consists of a palm (or manus)
and two fingers, one of which is movable (the dactylus or movable finger), whereas the other one
(Propodus/pollex) is fixed. The tips or edges of the fingers may be pectinated. In some families the
last pair or all walking legs are modified for swimming or burrowing, as seen in the Portunidae
(Carpenter and Niem, 1998).
