Portunidae is a family of crabs which contains the swimming crabs. Its members include well-known shoreline crabs such as the blue crab ( Callinectes sapidus ) and velvet crab ( Necora puber ).

Description

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

Swimming crabs reach their greatest species diversity in the Pacific and Indian Oceans.^{[ citation needed ]} Portunidae consists of the following subfamilies and genera: ^{[2] [a]}
