Comments: Specimens were collected from the base of a coral block on a reef flat with mixed sand and flat rock with patches of dead corals, from within live coral head in a sheltered bay, from a fringing reef at a depth of 1-3 m and from an isolated coral block. All were collected in close association with sea urchins of the genus <i>Diadema</i>, utilizing the long spines for shelter (Ref. 103877).
