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. A slow moving crab.
Features: Body width 4-5cm. Body
teardrop-shaped with large spines on the sides. Pincers long and cylindrical.
Body and walking legs covered with filaments and some have small bits
and pieces stuck on their bodies, but they are not as well 'decorated'
as the Velcro crabs (Camposcia retusa).
