Schizophrys sp.*
Family Majidae

Dec 2016
Where
seen? This large squat crab is sometimes seen on some of
our shores, clinging to coral rubble, large boulders or hiding under
living corals. Relying on its camouflage, the crab moves slowly.
Features: Body width 4-5cm. Body
teardrop-shaped with large spines on the sides. Large eyes on short
stalks with a pair of spines between them. Pincers long cylindrical,
tucked downwards under the body, claws with spoon-shaped tips. Body
and walking legs usually covered with encrustations, except for the
ends of the pincers. Some may have small bits and pieces stuck on
their bodies, but they are not as well 'decorated' as the Velcro
crabs (Camposcia retusa). |
