簡短描述 檢索表 | 型態特徵 | 形態測量圖

背棘 (總數) : 10 - 11; 背的軟條 (總數) : 14 - 16. Has a tall dorsal fin and small tufts below the chin (Ref. 48636). Resembles P. thepassii and P. variabilis but usually has fewer total dorsal fin elements (Ref. 37816).
在下巴之下有一個高的背鰭與小的簇。 (參考文獻 48636) 與 P. thepassii 與 P. variabilis 相似但是通常有較少的總背鰭要素.(參考文獻 37816)

生物學特性     字彙 (例如 epibenthic)

Adults occur solitary (Ref. 90102) usually over sandy areas of reef flats and shallow lagoons. Small juveniles were found below the upside-down jelly Cassiopea that moves over sandy substrates providing safe travel (Ref. 48636). Eggs are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Females nest in empty mollusk shells (Ref. 1602). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

出現於礁石平臺與潟湖淺灘的沙地。 築巢在空的軟體動物外殼中。 小的稚魚在移動沙的底部之上，而且提供了的上下顛倒的水母 Cassiopea 之下被發現 , 保險箱移動。 (參考文獻 48636)
