Etymology: Priacanthus: Greek, prion = saw + Greek, akantha = thorn (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; demersal; depth range ? - 350 m (Ref. 100719). Tropical
Indo-West Pacific: Red Sea and Reunion to Japan, northern Australia and Samoa. Mediterranean (Ref. 96612).
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 35.0 cm SL male/unsexed; (Ref. 48635)
soft rays: 13 - 15. Medium-sized fish. The body is oval; dorsal fin continuous; eyes very large; mouth large and oblique; preopercular spine short and broad. The head and body reddish silvery or, alternately, pale yellowish with gray mottling; the iris of the eye pink to bright red. The dorsal, anal, and caudal fins pink with reddish-brown spots in the membranes, or yellowish with dusky spots. This species resembles P. blochii, but differs from it by having pointed soft dorsal and anal fins, and black membrane between the first and the second dorsal spine.
In sheltered reefs in moderate depths, usually in caves or under coral plates (Ref. 48635); may also be found in rocky and open areas. Solitary (Ref 90102).

Estimates based on models
Phylogenetic diversity index (Ref. 82804
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01738 (0.00761 - 0.03969), b=2.92 (2.73 - 3.11), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Trophic level (Ref. 69278
): 4.2 ±0.6 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153
): Low to moderate vulnerability (33 of 100).
