Priacanthidae (Bigeyes or catalufas)
Etymology: Pristigenys: Greek, pristis = saw + Greek, genys, -yos = face (Ref. 45335).
More on author: Cuvier.
Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; depth range 1 - 250 m (Ref. 100719), usually 5 - 30 m (Ref. 94109). Tropical
Western Pacific: Japan, East China Sea Shelf, Taiwan, South China Sea, Vietnam, Celebes, Australia, and Indonesia.
Size / Weight / Age
Maturity: Lm ? range ? - ? cm
Max length : 27.4 cm SL male/unsexed; (Ref. 5403)
Dorsal spines (total): 10; Dorsal soft rays (total): 11; Anal spines: 3; Anal soft rays: 10; Vertebrae: 23. This species is distinguished from its congeners by the following set of characters: D X,11; A III,10; total gill rakers on first arch 27-31, mode 27 (upper limb 7-10, lower 19-22); lateral-line scales 31-39, mode 35; body scales above pectoral fin with about 11-60 spinules on posterior margin, the number increasing with growth; generally rounded caudal fin in young, becoming somewhat double emarginate in adults (noticeable in specimens over 15.0 cm SL); absence of black margins on posterior soft portions of vertical fins; 5 white or pale vertical bands (often indistinct) on body about 1/2-3/5 width of pupil expanded ventrally and dorsally with latter angled posterodorsally, very notable in young, less obvious in adults (Ref. 94109).
Body shape (shape guide): short and / or deep; Cross section: compressed.
Associated with rocky habitats and known from 80 to more than 100 m depth but probably also occurring in shallower water, especially as juveniles (Ref.5403). From dive observations, juveniles and young individuals likely occur at 5-30 m depths (Ref. 94109). Eggs are pelagic (0.75 mm), small and spherical.
