Citation: Randall et al. (1997); Fishbase(2005); Fishes of Japan(Nakabo, 2002)
Character: Dorsal rays XIII, 12-13; Anal rays II, 12-14; pectoral rays 17-18; lateral-line scales 19-20; body depth 2.5-2.8 times in standard length. Upper and lower accessory caudal rays not spinous. Posterior margin of preopercle and subopercle serrated. Both jaws with uniserial teeth. Upper and lower lobes of caudal fin without filamentous posterior rays. Body pale grey to bluish with a small black spot at base of upper pectoral rays. 
Habitat: Found mainly along continental margins rather than truly oceanic areas. Inhabits flat sandy or rubble bottoms around patch reefs of lagoons and trawling grounds. A somewhat unusual damselfish in behavior. Adults often seen in small groups out in the open  
Distribution: Distributed in the Indo-West Pacific from Red Sea and Persian Gulf to the Ryukyu Islands, Taiwan, Indonesia, New Guinea, and northern Australia. It is found in southern, southwestern and northeastern Taiwanese waters, and Penghu Islands. 
Utility: Aquarium fishes.

Biology     Glossary (e.g. epibenthic)

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 ).
