Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 111 - 113; Anal spines: 0; Anal soft rays: 88 - 91. Robust body with rounded snout; eye diameter much shorter than snout; opercular spine strong; 2 median and a pair of basibranchial tooth patches; 7-11 developed rakers on anterior gill arch; pelvic fin rays flattened distally and somewhat thicker in males (Ref. 34024).

Benthopelagic at bathyal and abyssal depths (Ref. 56809). Rare species (Ref. 34024). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Minimum depth reported taken from Ref. 4103.

Estimates based on models

Preferred temperature (Ref. 123201): 1.8 - 2.9, mean 2.2 °C (based on 1908 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00167 - 0.00864), b=3.14 (2.94 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (19 of 100).
