Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 36 - 37; Anal spines: 0; Anal soft rays: 28 - 31; Vertebrae: 42. This species is characterized by the following: superior and oblique mouth; body high at the occiput (humpbacked); upper nasal pore slightly posterior to vertical through nostril; with coronal pore; infraorbital canal interrupted posterior to the eye; pores of io 5 + 1 = 6; operciular opening above pectoral-fin base; head 24-25%, anteanal distance around half SL (Ref. 44814).

Occurs in the continental slope (Ref. 7300).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00525 (0.00237 - 0.01161), b=3.15 (2.96 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.6 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).
