Short description Identification keys | Morphology | Morphometrics

Barbel with five simple, tapering branches apparently arising together from main stem (lateral pair actually arising from the bases of the medio-lateral pair just distal to stem); medial branch longest, its length three times distal barbel; stem pigment extending up to terminal bulb; bulb short, barely greater in diameter than stem, bearing a single simple terminal filament (Ref. 45801).

Epi- and mesopelagic (Ref. 58302).

Estimates based on models

Preferred temperature (Ref. 123201): 5.5 - 13.6, mean 7.8 °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

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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