Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Vértebras: 158 - 162. Body uniformly grayish or brown to nearly black. Dorsal fin origin well behind pectoral fin tips; pectoral fin rounded, not elongate and well-developed. Posterior nostril a hole above the upper lip, covered by a flap that extends to or below the edge of the mouth. Upper lip lacks barbels between anterior and posterior nostrils. Pores small but conspicuous, SO 1 + 4, IO 4 + 2, POM 6 +2. Teeth small and conical, biserial on anterior vomer and jaws (Ref. 40865).

This species is captured by trawl over sand and muddy bottom between 36-1350 and observed from submersibles to be most abundant between 250-350 m, with only the heads exposed over sandy substrates or resting on the sediment with their bodies in S-shaped curves (Ref. 86730). Mature females collected 48-62.8 cm TL (Ref. 40865).

Estimates based on models

Preferred temperature (Ref. 123201): 11.8 - 17.3, mean 14.5 °C (based on 12 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00089 (0.00039 - 0.00204), b=3.00 (2.80 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.9 ±0.7 se; based on size and trophs of closest relatives

Resiliência (Ref. 120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).
