Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenweichstrahlen (insgesamt) : 24; Afterflossenweichstrahlen: 39; Wirbelzahl: 68. Two terminal bulbs separated by an interspace, 1.2-2.4 times the length of distal bulb. Barbel length mostly 31-71% SL in specimens less than 8 cm; 67-91% SL in larger ones. Terminal filaments short, 4-6 without prominent bulblets, arising together from distal bulb or from a short distal stem; 1 filament thicker and longer than others. Pigment in filament axes variably present or absent. Distal bulb spheroidal to ovoid, not much longer than wide, 1.5-4.3 times proximal-bulb length. Axis of stem usually lightly pigmented, between bulbs unpigmented or lightly pigmented; dark spot present or not at proximal end of distal bulb. External chevron-shaped or roundish striated areas on stem unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 8, sometimes 9 (Ref. 11333).

Mesopelagic (Ref. 58302).

Estimates based on models

Preferred temperature (Ref. 123201): 5.8 - 15.2, mean 8.9 °C (based on 6 cells).

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

Bayesian length-weight: a=0.00302 (0.00117 - 0.00783), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.8 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).
