Species of crab

Grapsus tenuicrustatus, commonly known as thin-shelled rock crab[1] or Natal lightfoot crab,[2][3] is a species of decapod crustacean in the family Grapsidae.

The English common name natal sally-light-foot crab has been applied to the species by the FAO,[4] and as the synonym Grapsus grapsus tenuicrustatus suggests, it had sometimes been classified as a subspecies of the sally-lightfoot.[5]

Carapace is a deep purple, almost black, with delicate lacy white markings all over its carapace and legs.[1]

It is found in Hawaii and the Indo-Pacific, and known as ʻaʻama in the Hawaiian language.[6][7][8]
