Short description Bestämningsnycklar | Morfologi | Morfometri

Dark grey dorsally, white ventrally (Ref. 26346).

Found on the continental shelf and upper slope (Ref. 26346). Feeds on fish, probably at night (Ref. 26346). Ovoviviparous (Ref. 50449).

Life cycle and mating behavior Könsmognad | Reproduktion | Lek | Ägg | Fecundity | Larver

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 9.5 - 14.1, mean 12 °C (based on 33 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01479 (0.00665 - 0.03288), b=2.96 (2.77 - 3.15), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 4.5 ±0.80 se; based on food items.

Resiliens (Ref. 120179): Mycket låg, lägsta populationsfördubblingstid mer än 14 år (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).
