Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; reef-associated; depth range 0 - 55 m (Ref. 54832). Tropical

Distribution Territories | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-Pacific: South Africa to the Red Sea and from the Philippines to Cape York Peninsula in northern Australia; widely distributed and large gap in the distribution is probably a collecting artefact rather than indicative of a true distribution.
