Spanner crab

The large, orange Spanner crabs Ranina ranina usually inhabit deep water from 5 to 50 metres, but they are occasionally found on the lagoon beaches at low tide, but quickly burrow down into the sand when disturbed. The name is derived from the unusual shape of the claw, which looks just like an adjustable wrench or spanner. These are harvested commercially on the mainland as an edible crustacean.
