Biologie     Glossaire (ex. epibenthic)

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). May be found solitary or in groups (Ref. 90102). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 113699).
