Infra-order Brachyura, Family Grapsidae

Mottled lightfoot crab | Grapsus albolineatus  Lamarck, 1818 ​

Very similar in size and coloration to Grapsus crab. Up to 50–60 mm carapace width. Mottling on the legs is such that distinct stripes are formed from darker color. Claws are mauve to pink.



Found in the intertidal zone to 5 metres above sea level, generally on reefs and rocky shorelines. Active at night and seldom seen during daylight. Very shy, disappearing instantly into crevices at the slightest sign of

danger.
