Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 0; Raios dorsais moles (total) : 13 - 15; Espinhos anais: 0; Raios anais moles: 14 - 16; Vértebras: 47 - 50. Branchiostegal rays: 10-12 (Ref. 36576).
Adults are found near shore, frequently in coastal bays at or near the surface. Often form small schools. Occasionally penetrate fresh waters (Ref. 9306). Presumably oviparous, with planktonic larvae (Ref. 36576). Eggs are attached to spawning substrate via filaments (Ref. 36576).
