Dorsale stekels (totaal) : 0; Anale stekels: 0. Head large; eyes large; snout pointed, its anterolateral margin incompletely supported by bone. Underside of the head mostly scaled. Light organ large, a lens-shaped fossa on the abdomen extending forward to midway between the anus and the pelvic fin insertions. Scales on body with small imbricate spinules arranged in as many as 24 rows. Swim bladder deeply bilobed anteriorly, pointed posteriorly.

Estimates based on models

Preferred temperature (Ref. 115969): 8.5 - 16, mean 13.6 (based on 55 cells).

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00200 (0.00124 - 0.00320), b=3.20 (3.06 - 3.34), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.7 ±0.5 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Zeer laag, minimale populatieverdubbelingstijd meer dan 14 jaar (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (49 of 100).
