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
Ökologie
seewasser riff-verbunden; tiefenbereich 1 - 250 m (Ref. 100719), usually 5 - 30 m (Ref. 94109). Tropical

Size / Gewicht / Alter
Maturity: Lm ? range ? - ? cm
Max length : 27.4 cm SL Männchen/unbestimmt; (Ref. 5403)
Rückenflossenstacheln (insgesamt): 10; Rückenflossenweichstrahlen (insgesamt): 11; Afterflossenstacheln 3; Afterflossenweichstrahlen: 10; Wirbelzahl: 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).
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.
