Homolidae

The family Homolidae, known as carrier crabs[1] or porter crabs,[2] contains 14 genera of marine crabs. They mostly live on the continental slope and continental shelf, and are rarely encountered.[3] Members of the Homolidae have their fifth pereiopods (last pair of walking legs) in a sub-dorsal position, which allows them to hold objects in place over the rear half of the carapace.[3] The objects carried include sponges, black corals and gorgonians, and this behaviour may be a defence mechanism against predators.[3] Some species have been observed carrying living sea urchins in a symbiotic relationship which allows them to benefit from the protection of the urchin's dangerous spikes.[4][5][6][7]
