Etymology: Priacanthus: Greek, prion = saw + Greek, akantha = thorn (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range 150 - 400 m (Ref. 5403). Deep-water
Western Pacific: southern Japan to northwestern Australia.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 18.5 cm SL male/unsexed; (Ref. 5403)
soft rays: 13 - 14. Medium-sized fish. The body is oval; dorsal fin continuous; eyes very large; mouth large and oblique, with the lower jaw projecting upwards. The head and body silvery red or pink; iris of eyes red. The fins are creamy pink; the last 4-5 soft rays of the dorsal and anal fins are clearly white. This species resembles P. macracanthus with a long and narrow preopercular spine, but has less body depth, a narrower caudal peduncle, and fainter yellowish spots on its dorsal, anal and pelvic fins.
A deeper water species trawled from relatively open bottoms at depths of 150 to over 400 m.
