Environment:  reef-associated; marine; depth range 12 - 400 m, oceanodromous
Distribution:  Western Pacific: southern Japan to western Indonesia, the Arafura Sea (Ref. 9819), and Australia. Reported from Peter the Great Bay (Ref. 27683).

The eyes large; the mouth oblique, with the lower jaw projecting upwards. The body tapers very slightly to beneath the middle of the soft portion of the dorsal fin, and then abruptly to the peduncle. This species is distinguished from P. fitchi by the presence of numerous rusty brown to yellowish spots in the membranes of the dorsal and anal fins, and its less tapered body.

Apparently forms aggregations in open bottom areas and is very abundant in the South China Sea and Andaman Sea. Marketed fresh, whole. Sound production has been studied in this species. Also found under ledges or hovering next to coral heads during day (Ref 90102).
