真實的 D. prosopotaenia 是白色的-在上側面上胸部了而且缺乏大的黑色斑塊; 胸部黃色的變化有黑色的斑塊。 (參考文獻 48636)
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).
棲息於潟湖與岸礁, 通常在淤泥的區域.(參考文獻 4966) 真實的 D. prosopotaenia 範圍從新加坡到蘇拉威西然而胸部黃色的變種範圍從伊裡安加亞到澳洲東部與萬那度.(參考文獻 48636)
