Identified by its host, the branching black coral (Antipathes sp.), X. conicus is able to transfer living matter from its host onto its carapace and leg joints for camouflage.
Typically found in the Indo-Pacific region.
Spotted these critters on a bush-like coral at a depth of probably 12m during a day dive. There were two of them: the first 2 photos show one, and the other two show the other. The latter seems to have thicker appendages, and you can just make out the claw in the 3rd photo. (Just to be sure you can see the critter clearly, the 3rd & 4th photo shows it hanging upside down.)
