Environment:  benthopelagic; marine; depth range 0 - 3 m
Distribution:  Western Indian and Southeast Atlantic: from Mozambique (Bazaruto) to South Africa. Speciimens collected from Shimoni, Kenya may refer to the species but are in poor condition so until additional specimens are available, Bazaruto is considered its most northern limit (Ref. 75031).
