Often confused with the juveniles from other crabs in this family, this small crab has a mottled brown green to grey body and features three small notches behind the eye on the side of the carapace and like all the other shore crabs they feed on the decaying fish and seaweeds found along our beaches and scurry away to find shelter when disturbed.
The first of the notches is slightly more forward (closer to the eye) than the last two set on a slight angle the front of the carapace is angled downwards with the eyes at the corner of the carapace.
