Grootte / Gewicht / Leeftijd
Maturity: Lm ?  range ? - ? cm
Max length : 16.0 cm SL mannelijk / geslacht onbekend; (Ref. 559)
Dorsale zachte stralen (totaal) : 24; Anale zachte stralen: 36; Wervels: 68. Two terminal bulbs separated by a very short interspace (0.5-0.6 times length of distal bulb). Barbel 50-53% SL. Terminal filament short, 4.1-5.3% SL without branches. Distal bulb 1.8 times length of proximal bulb in small specimens, 0.7 in larger ones. Proximal bulb in larger specimens large for its size, 1.5 mm at 118 mm SL. Barbel without pigment in smaller specimens; larger ones with fairly dense pigment in proximal part of axis, little or none in distal part. External chevron-shaped or roundish striated area on stem not pigmented. Middorsal paired spots between occiput and dorsal-fin origin 8 (Ref. 11333).
Mesopelagic species (Ref. 559).

Estimates based on models
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 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).
Trofisch niveau (Ref.
69278): 4.3 ±0.8 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
