Short description Morphology | Morphometrics

Dorsal spines (total): 10 - 17; Anal spines: 0; Anal soft rays: 16 - 22; Vertebrae: 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.

Biology     Glossary (e.g. epibenthic)

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).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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).
