Christmas Island crabs, sandy rubble crab, cyclograpsus integer, Christmas Island, Max Orchard

A small crab growing up to 20 mm carapace width. Found in sand and coral rubble in the intertidal zone on most of the island beaches.

This species is currently under review, as the distribution of this species is far ranging, and the species from East Asia seem to be slightly different from those collected in the Atlantic.
