Sponge Crab

Stimdromia lamellata

Systematics: Brachyura Family Dromiidae

Distinguishing Characters:
The smooth white carapace is strongly domed and camouflaged by a sponge. The last legs end in tiny pincers which can only be seen when the sponge is taken off. The carapace is up to 22 mm across.

Habitat and Distribution:
These animals are likely to be seen living under rocks in pools on rock platforms, jetty piles, kelp holdfasts and in sandy environments rich in sponges.

General Biology:
Species of this family are commonly referred to as sponge crabs because they carry about with them a piece of living sponge, sea squirt, soft coral or shell. The picture above is an example of a 'naked' animal that has had the sponge removed from its carapace. To see the camouflaged version click on the subheading "General biology".
