Short description Identification keys | Morphology | Morphometrics

Dark brown, becoming blackish on the gular and branchiostegal membranes. Inside of mouth and gill cover black. Head fully scaled, mandibular band is narrow (Ref. 37108). Orbit tiny, about 10% of head length, placed forward of small, inferior mouth. Chin barbel absent. First gill slit not restricted by membranous folds of skin, outer gill rakers long, slender. Branchiostegal rays 7. Anus immediately before anal fin. Tail straplike. Anal fin long, poorly developed. No light organ. Swimbladder regressed. (Ref 1371)

Live at midwater as well as benthopelagic levels (Ref. 37108).

Estimates based on models

Preferred temperature (Ref. 123201): 3.5 - 9.1, mean 5.3 °C (based on 733 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00309 (0.00119 - 0.00804), b=3.12 (2.90 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (25 of 100).
