Remarks. – This is a common species throughout the Indo- West Pacific region, from the Red Sea and the Persian Gulf to Tahiti, though it has not been recorded from Japan or the southwest Indian Ocean ( Guinot-Dumortier, 1960). The live specimens are drab in colour, with a splotchy mix of light and dark browns as well as gray in some specimens, which probably help the crab camouflage itself in the intertidal and shallow subtidal areas where it lives.
