Description synthétique
Clés d'identification | Morphologie | Morphométrie
Épines dorsales (Total) : 10 - 17; Épines anales: 0; Rayons mous anaux: 16 - 22; Vertèbres: 41 - 45. Silvery-white with black melanophores surrounding each scale on the dorsal two-thirds of the body. The dorsal half of the body is almost translucent.
Body shape (shape guide): fusiform / normal.
Adults usually occur in large schools near surface in open water, over dark sandy bottom (Ref. 35360). Well adapted to a life of heavy predation (Ref. 35360). Frequent skipping over the water surface is observed apparently in avoidance of predators (Ref. 35360).
Based on otolith data, these species spawn after their first winter and that only a small segment of the population lives through the second winter (Ref. 35360).
