Descripción breve
Claves de identificación | Morfología | Morfometría
Espinas dorsales (total) : 6 - 10; Radios blandos dorsales (total) : 8 - 14; Espinas anales: 1; Radios blandos anales: 19 - 25; Vértebra: 44 - 52. Blue gray to green above, silvery below; a striking silver band bordered above with blue extends the full length of the body (Ref. 6885). Branchiostegal rays: 5-6 (Ref. 36497).
Body shape (shape guide): elongated.
Common in bays, muddy and rocky areas and kelp beds, also in estuaries (Ref. 36497). Form schools. Adults feed on zooplankton (Ref. 9273), while juveniles feed on algae and kelp fly larvae (Ref. 4930). Demersal spawner in nearshore habitats (Ref. 56049). Oviparous, with planktonic, primarily neustonic larvae (Ref. 36497). Eggs are attached to spawning substrate and to one another by adhesive filaments (Ref. 36497).
