Etymology: Pristigenys:Greek, pristis = saw + Greek, genys, -yos = face (Ref. 45335). More on author: Cuvier.
Meio ambiente: milieu / Zona climática / intervalo de profundidade / faixa de distribuição Ecologia
marinhas associadas(os) a recifes; intervalo de profundidade 1 - 250 m (Ref. 100719), usually 5 - 30 m (Ref. 94109). Tropical
Espinhos dorsais (total) : 10; Raios dorsais (total) : 11; Espinhos anais: 3; Raios anais : 10; Vértebras: 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.
