Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 9 - 11; Anal spines: 0; Anal soft rays: 18 - 21; Vertebrae: 48 - 53. Head and body silver when fresh; no scale pocket markings; lateral line indistinct (Ref. 13608). Slender body. Jaws rounded and subequal at the tips (Ref. 37473). Body strongly elongated with almost equal depth. Caudal peduncle short and relatively narrow. Pectorals short, far from reaching origin of dorsal fin. Radial pattern noticeable at the hind lower part of operculum. Few gill rakers on the inner surface of epibranchial of first gill arch (Ref. 33679).

Biology     Glossary (e.g. epibenthic)

Mesopelagic (Ref. 58302). Usually caught in small aggregations (Ref. 6345). Exhibits daily vertical migrations (Ref. 6345). Feeds on plankton (Ref. 6345).

Estimates based on models

Preferred temperature (Ref. 123201): 8.8 - 19, mean 13 °C (based on 406 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00525 (0.00219 - 0.01260), b=3.01 (2.80 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±0.45 se; based on food items.
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (11 of 100).
