General Description

Carapace wider than long, dorsal surface with few or many setae, becoming a dense band of long setae marginally and extending on to front and sides of carapace.

Biology

Hairy crabs of the family Pilumnidae are slow-moving crabs more or less covered with a mat of hairs or velvet and often appearing dirty because of the mud trapped on the hairs. Bearded crabs are a commonly encountered pilumnid in dredge samples in Port Phillip Bay and Western Port in Victoria. Unlike other pilumnids there are few hairs dorsally.

Habitat

Common under rocks and rubble on sheltered reefs, and in mussel clumps on muddy sandflats, to 70 m depth.
