Environnement : milieu / zone climatique / profondeur / gamme de distribution
Écologie
marin; eau douce; saumâtre récifal; profondeur 0 - 10 m (Ref. 86942). Tropical
Indo-West Pacific: Somalia (Ref. 30573) and southern Africa to India and probably most other parts of the Indian Ocean. Found in New Guinea (Ref. 7050) and Tahiti (Ref. 12792). Record from the Mascarenes by Castle (1984, in distribution map, Ref. 7245) could not be verified; probably erroneous (Ref. 33390).
