Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Mjukstrålar i ryggfenan (totalt) : 13 - 15; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 14 - 16; Ryggkotor: 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).
