Short description Identification keys | Morphology | Morphometrics

Lack of thorns along the midbelt of the disc from the level of the axils of the pectoral fins to the vicinity of the spiracles. Tails widen rearward toward the dorsal fins. No interspace between the bases of the dorsal fins. Upper surface pale brown, darker along posterior margins of disc, pelvic fins and tail. Dorsal fins and caudal black. Lower surface margined with black rearward from the level of the mouth (Ref. 6902).

Found on upper continental slope (Ref. 114953). Oviparous (Ref. 50449). Eggs have horn-like projections on the shell (Ref. 205). Males reaches maturity at ca.63 cm TL (Ref. 114953).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 7 - 15, mean 10.1 °C (based on 115 cells).

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

Bayesian length-weight: a=0.00282 (0.00133 - 0.00596), b=3.25 (3.08 - 3.42), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

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

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (54 of 100).

Price category (Ref. 80766): Medium.
