Short description Morphology | Morphometrics

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

Biology     Glossary (e.g. epibenthic)

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 Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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

Estimates of some properties based on models

Preferred temperature (Ref. 115969 ): 6.4 - 12.9, mean 8.2 (based on 173 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00224 (0.00123 - 0.00406), b=3.25 (3.10 - 3.40), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245 ). Trophic Level (Ref. 69278 ):  4.1   ±0.6 se; Based on size and trophs of closest relatives Resilience (Ref. 69278 ):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
