Indo-Pacific: East Africa to the Line and Society Islands, north to Mariana Islands, south to the southern Great Barrier Reef; throughout Micronesia. Likely at Seychelles (Ref. 1623).

大小 / 重量 / 年齡
成熟度: Lm ?  range ? - ? cm
Max length : 7.5 cm TL 雄魚/尚未辨別雌雄; (Ref. 90102)
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).
Body shape (shape guide): elongated.
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)
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)
