Maturity: Lm ? range ? - ? cm
Max length : 40.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 9407)
背棘 (總數) : 5; 背的軟條 (總數) : 31 - 34; 臀棘: 3; 臀鰭軟條: 24 - 28. Juveniles have extremely elongate vertical fins and closely resemble juvenile P. teira, but tend to be lighter with a silvery hue. Adults have smoothly rounded head profile like P. orbicularis, but usually have golden hue and lack small black spots (Ref. 37816). Adults (above 18 cm) yellowish silvery, usually with small, scattered black spots on body, dark bar through eye, and another bar just behind head. Median fins yellowish green. Anal-fin margin and rear margin of caudal fin black. Pelvic fins black. Small juveniles yellowish brown or silvery, with 2 black bars as in adults. Rear third of body blackish, the black colour continued onto dorsal and anal fins, and the front of the black zone on body often closely precede by a narrow faint dark bar. Caudal fin transparent except for black base. Jaws with bands of slender, flattened, tricuspid teeth, the middle cusp barely longer than lateral cups (Ref 43039).
稚魚非常地有細長的垂直鰭而且非常近似稚魚 P. teira, 但是傾向顏色淡的具有一個銀色的色。 成魚有平滑圓形的頭部輪廓例如 P. orbicularis, 但是通常有金的色而且缺乏小的黑色斑點.(參考文獻 37816) 成魚 (上方 18 公分) 淡黃色的銀色, 通常有小的, 分散的黑色斑點在身體上, 經過眼 , 與另一條橫帶在頭部正後方的深色橫帶。 中央的鰭淡黃綠色的。 臀鰭邊緣與尾鰭黑色的後面邊緣。 腹鰭黑色。 小的稚魚土黃色或銀色的, 有兩個黑色的橫帶當當成魚時。 身體的後面第三黑色的, 黑色的顏色在背鰭與臀鰭之上繼續，而且黑色區域的前面在身體上時常接近地被一條狹窄模糊的深色橫帶之前。 尾鰭透明除了黑色的基底。 頜部有條紋細長的, 平的, 三尖齒, 中央的尖頭幾乎長度超過側部杯子 (參考文獻 43039).
Adults occur mostly in large schools along drop-offs, including outer reefs; singly in coastal waters. Juveniles are on deep slopes among tall coral formation (Ref. 48637). Benthopelagic (Ref. 58302).
成魚大部分出現在大群魚群沿著海峭壁, 包括外海岩礁; 各別地在沿岸水域中。
