Info

Monomia petrea (Alcock, 1899)

Portunidae is a family of crabs which contains the swimming crabs. Portunid crabs are characterised by the flattening of the fifth pair of legs into broad paddles, which are used for swimming.[2] This ability, together with their strong, sharp claws, allows many species to be fast and aggressive predators.
