Where
seen? This large crab with typical spoon-tipped pincers
is commonly seen on our Southern shores among coral rubble and near
living reefs.
Features: Body width 8-10cm. In
large crabs, the body is flat, with some blunt teeth on the edges
of the shell. The walking legs are fringed with long hairs and end
in pointed tips. The pincers are black with white spoon-shaped tips.
These are probably used to scrape off algae.
Colours and patterns in a wide variety; basically brown or grey, sometimes
with one or more white or yellow stripes from the front between the
eyes to about half way down the body.
Sometimes confused with Pilodius
rock crabs (Pilodius sp.) that look very similar but are
usually much smaller.
