Carapace with submarginal 1-3 tall erect spines near anterolateral margin and sometimes 1 behind orbit; frontal lobes separated by deep narrow notch, each lobe with tubercles; carapace, chelipeds and walking legs with even covering of stiff hairs, no clubbed setae. 38 mm.
As the name suggests, this is the most common hairy crab intertidally where it hides under boulders. Whereas many crabs will attempt to escape when disturbed or captured, pilumnud crabs play dead, curling their legs up to look as inconspicuous as possible. Their camouflage makes them difficult to see even when rocks are turned.
Subtidal to 310 m depth.
Southern temperate oceans, including southern Australia.
Not harmful but a nip from large claws could be painful
