Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 0; Rückenflossenweichstrahlen (insgesamt): 55-63; Afterflossenstacheln 0; Afterflossenweichstrahlen: 37 - 42. Pelvic fins with 6 rays (females), absent in males.

Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

Mesopelagic species (Ref. 75154). Pronounced sexual dimorphism: females are black, with well developed canine teeth, barbel and pelvic fins with six stripes. Males are dark-brown, have no teeth on maxilla and neither barbel nor pelvic fins (Ref. 47377). Apparently, females live below 500 m during the day and perform vertical migration at night to shallower depths; males always in deep water, ca 1,000-2,000 m (Ref. 5169).

Estimates based on models

Preferred temperature (Ref. 123201): 2.1 - 3.7, mean 3.1 °C (based on 311 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.6250   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  4.0   ±0.7 se; based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 120179):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (46 of 100).
