Indo-West Pacific: Natal, South Africa to the central Pacific. Not known from the Red Sea nor Persian Gulf.

Biology     Glossary (e.g. epibenthic)

Occur in outer reef flats and shallow lagoon (Ref. 37816). Reported to be taken in a trawl, thus presumably caught somewhat deeper than 7 m. Also reported to occur in reefs at a depth of about 30 m (Ref. 5213). Because of its small size and apparent rarity, it is of little or no commercial importance. Solitary (Ref 90102).
