(Bigeyes or catalufas)
Etymology: Priacanthus: Greek, prion = saw + Greek, akantha = thorn (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; reef-associated; non-migratory; depth range 3 - 230 m (Ref. 38732). Tropical
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.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 33.0 cm TL male/unsexed; (Ref. 9710)
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).
