Carrier crab (Homolochunia kullar). This crab lives at a depth of 500-1000 metres in the Pacific Ocean around New Caledonia and Eastern Australia. Unusually, it has rear and front pincers. The rear pincers, located at the tip of its last pair of legs, enable the crab to grasp sponges or sea anemones, which it holds above itself for camouflage. Carrier crabs (family Homolidae) are primitive crabs, and have their sexual orifices at the base of their legs on the under side, whereas the more advanced crabs have these sexual orifices under the breastplate. The carapace (shell) of this specimen measures 3cm wide.
