Body smooth, circular and mottled light and dark green-grey. Three triangular teeth on rear of the carapace. Up to 4 cm wide (carapace).

Biology

Many Pebble Crabs are apparently nocturnal; they can be found partly buried in the soft mud of intertidal seagrass meadows during the day. At night they use their long chelipeds (legs with claws) to capture small invertebrates, though they also may scavenge dead material. Large male Pebble Crabs have longer claws than the females.

Distribution

South-eastern Australia.

Habitat

Muddy areas, to depth of 95 m.
