Short description Morphology | Morphometrics

This species is distinguished by the following characters: almost no scales on the ventral surface of the head; nasal fossa with a large scaleless area anteriorly extending to nasal ridge and ventrally to or near suborbital ridge; lacks external evidence of a light organ; anus immediately before anal fin origin; long snout, about 2.0-2.3 into head length (HL), with strong terminal scute, which is elongate ventrally, anterolateral margins not completely supported by bone; grayish brown body, no prominent marking s; narrow blackish eye ring; dusky to black lips, mouth, and gill cavities (Ref. 80968).

Biology     Glossary (e.g. epibenthic)

Apparently a deepwater species and have a very low abundance as it was taken only in small numbers (Ref. 80968).

Estimates based on models

Preferred temperature (Ref. 123201): 2.9 - 4.9, mean 4 °C (based on 173 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00251 (0.00128 - 0.00492), b=3.19 (3.03 - 3.35), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Very Low, minimum population doubling time more than 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low to moderate vulnerability (35 of 100).
