Diagnosis: 15-16 gill rakers on first ceratobranchial; preorbital 16.7-17.5% HL; teeth in outer rows on dentary and premaxilla of mature males small and bicuspid (Ref. 57549).

Feeds on plankton, and basied on the shape and the silvery coloration, probably lives over sand in the open water (Ref. 5595).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.4 ±0.45 se; based on food items.

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Prijsklasse (Ref. 80766): Unknown.
