Short description Identification keys | Morphology | Morphometrics

Snout rather blunt; eye diameter almost as long as snout; opercular spine strong and straight; hind margin of preopercle usually with 3 sharp spines; 1 median (broad) and a pair of basibranchial tooth patches; pseudobranchial filaments 2 or 3; 7-15 developed rakers on anterior arch; lower 5-11 pectoral fin rays free and longer than upper ones; precaudal vertebrae 13-16 (Ref. 34024). Caudal fin and posterior part of dorsal and anal fins black (Ref. 34024).

Benthopelagic at bathyal depth (Ref. 56809). Rare species (Ref. 34024). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Minimum depth reported taken from Ref. 559.

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 7.4, mean 5.4 °C (based on 64 cells).

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

Bayesian length-weight: a=0.00110 (0.00040 - 0.00297), b=3.08 (2.85 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.7 ±0.6 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): Moderate to high vulnerability (48 of 100).
