Short description Claves de identificación | Morfología | Morfometría

Grey with scattered charcoal blotches dorsally, greyish-white ventrally (Ref. 26346).

Occurs in coastal waters, continental shelf and upper slope (Ref. 26346). Usually found in deeper waters to 200 m (Ref. 9258). Mainly feeds on benthic decapods and bony fishes (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca. 150 cm TL. This species is said to be long lived and slow growing (Ref. 114953).

Life cycle and mating behavior Maturities | Reproducción | Spawnings | Egg(s) | Fecundities | Larva

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Young hatch at about 20-23 cm (Ref. 26346).

Estimates based on models

Preferred temperature (Ref. 123201): 6.4 - 12.9, mean 8.2 °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=0.00224 (0.00133 - 0.00376), b=3.23 (3.09 - 3.37), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 4.1 ±0.6 se; based on size and trophs of closest relatives

Generation time: 11.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliencia (Ref. 120179): Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Very high vulnerability (80 of 100).

Price category (Ref. 80766): Medium.
