Etymology: Priacanthus: Greek, prion = saw + Greek, akantha = thorn (Ref. 45335).
Environment / Climate / Range
Marine; reef-associated; non-migratory; depth range 3 - 230 m (Ref. 38732). Tropical
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 33.0 cm TL male/unsexed; (Ref. 9710)
Eastern Pacific: Hawaiian and Midway Islands; a single juvenile specimen recorded from the Galapagos Islands. Strays reach Johnston Atoll (Ref. 9710). Reports from Japan are probably misidentifications of Priacanthus hamrur.
Inhabit clear lagoon and seaward reefs. Found under ledges during the day (Ref. 9710). Benthopelagic (Ref. 58302). Spawning may occur by December or soon after. Sound production has been studied in this species (Ref. 5403).

Phylogenetic diversity index (Ref. 82805
= 0.5002 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (-0.30300 - 0.32300), b=3.04000 (2.92100 - 3.15900), based on all LWR estimates for this BS (Ref. 93245
Trophic Level (Ref. 69278
): 4.2 ±0.73 se; Based on food items.
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (23 of 100) .
