Coleman’s shrimp (Periclimenes colemani), on Fire urchin (Asthenosoma varium), and a white snail (Leutzenia asthenosomae). Usually found in pairs, these commensal shrimps live exclusively on Fire urchins, where they occupy a patch that has been cleared of tube feet and spines. The relationship between shrimps and urchin is harmless, commensal, but the snail is a parasite feeding on the body fluids and tissue of the urchin. Anilao, Manila, Philippines
