General Description

Body grey, flattened and covered with hairs. Legs held close together and claws flat and wide. Antennae blue. Up to 3 cm wide (carapace).

Biology

Hairy Stone Crabs differ from true crabs because they only have three pairs of obvious legs besides the claws. They rely on their muddy appearance as a camouflage, clinging invisibly to the undersides of rocks rather than fleeing from predators.

Under rocks on exposed rocky shores.
