Usually identified as P. jerdoni (Day, 1873), a junior synonym (Ref. 48636). Adults are found mainly along continental margins rather than truly oceanic areas. Inhabits flat sandy or rubble bottoms around patch reefs of lagoons and trawling grounds (Ref. 7247). Adults often seen in small groups out in the open on sandy substrate, swimming well-above the bottom and unlike other damselfishes rely on speed to get away from predators rather than diving into the shelter or reefs or burrow. Juveniles often shallow estuaries, but adults mainly in deeper water offshore at depths of 20+ m and have been reported to 80 m depth (Ref. 48636). 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. 54980; 113699).
通常鑑定為 P. jerdoni(日子,1873) ，一個次同種異名。 (參考文獻 48636) 主要地發現沿著大陸的邊緣而不是真實大洋性的區域。 潟湖與拖網漁場的礁坪周圍棲息於平坦的沙或碎石的底部。 (參考文獻 7247) 一隻行為有些不尋常的雀鯛。 出自砂質底部上的開放水域成魚常被見到形成小群魚群, 游泳離底部一段距離與不像其他的雀鯛仰賴速度得到遠離掠食者而不是潛水進入庇護所或者礁之內或者掘洞穴。 稚魚時常水淺的河口, 但是成魚主要在水較深的外海深度 20+ 公尺而且曾經報告 80 公尺深.(參考文獻 48636)
