Kurzbeschreibung Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt): 3; Rückenflossenweichstrahlen (insgesamt): 13; Afterflossenstacheln 1; Afterflossenweichstrahlen: 9 - 10; Wirbelzahl: 27 - 28. The species is distinguished by the following characters: spined posterior and lower margins of the praeoperculum, in the angular part of it is an unspined notch; insertion of the ventral fins is in front of the vertical of the posterior margin of the pectoral fin insertion; upper jaw extends beyond the vertical of the posterior eye margin; soft rays in dorsal fin 13, in anal fin 9-10; first branchial arch with 31-33 rakers; vertebrae 27-28; pyloric caeca 8 (Ref. 83719).

Specimens were seined with non-closing fishing gear in the range of depths 3000-0 m and with bottom fishing gear is seined at 1640-2000 m (Ref. 83719).

Estimates based on models

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

Bayesian length-weight: a=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.3 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): sehr niedrig, Verdopplung der Population dauert mehr als 14 Jahre. (Preliminary K or Fecundity.).

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