Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 37; Wirbelzahl: 42. Skin pale, peritoneum blackish-brown, mouth and gill cavity pale. Coronal pore present. Mouth strongly oblique, angle 73-75°. Eyes very small, 14% HL. Branchial cavity large with ventrolateral part prominent, covering base of pectoral fin. Gill rakers unmodified. Pectoral fin insertion low, almost horizontal (Ref. 43481).

Caught between 0 and 2000 m depth over 3900 m depth. Assumed to be bathydemersal (Rainer Froese, pers. comm.).

Estimates based on models

Preferred temperature (Ref. 123201): 5.2 - 11.5, mean 7.9 °C (based on 58 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00237 - 0.01161), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±0.5 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

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