FAMILY : DROMIIDAE
Stimdromia lateralis (Gray, 1831)?

Species of Dromiidae are often referred to as sponge crabs because of their habit of carrying a live sponge on their back (carapace).
This is made possible by the last two pairs of legs being clawed and smaller than the others and gripping onto the sponge.
Dromiids are regarded as very primitive crabs.
