Spoon-pincer crab
Leptodius sp.*

Family Xanthidae
updated Sep 11
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.
