Indo-West Pacific: Nicobar Islands to Vanuatu, north to the Ryukyu Islands, south to northwest Australia and the Great Barrier Reef (Ref. 9710).
Adults inhabit lagoons and coastal reefs, usually in silty areas (Ref. 4966). The true D. prosopotaenia ranges from Singapore to Sulawesi while the yellow-breasted variant ranges from Irian Jaya to eastern Australia and Vanuatu (Ref. 48636).
