Short description Claves de identificación | Morfología | Morfometría

Large width interspace between first and second dorsal fins. Upper surface pale brown disc without definite markings. Lower surface whitish or yellowish. Tail pale dusky below (Ref. 6902).

Deep water species (Ref. 6902). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 123201): 7.4 - 13.7, mean 9.5 °C (based on 24 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00661 (0.00222 - 0.01969), b=2.95 (2.71 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

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

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (35 of 100).

Price category (Ref. 80766): Medium.
