The species was found along the coasts of the islands, a combination of mangrove, rocky shore, and an occasional sand beach; the inshore habitat of the islands consists of low-diversity, fringing coral reef exposed to turbidity and siltation, underwater visibility often less than 3 m where the tidal current can be very strong (Ref. 85096).
