Portunidae is a family of crabs which contains the swimming crabs. Its members include many well-known shoreline crabs, such as the blue crab (Callinectes sapidus) and velvet crab (Necora puber). Two genera in the family are contrastingly named Scylla and Charybdis; the former contains the economically important species black crab (Scylla serrata) and Scylla paramamosain.

Description

[edit]

Portunid crabs are characterised by the flattening of the fifth pair of legs into broad paddles, which are used for swimming.[1] This ability, together with their strong, sharp claws, allows many species to be fast and aggressive predators.[1]

Taxonomy

[edit]

Swimming crabs reach their greatest species diversity in the Pacific and Indian Oceans.[2] The following species are recognized in the family Portunidae:
