Length at first maturity / Tamanho / Peso / Idade

Maturity: L_m 64.7, range 56 - ? cm
Max length : 75.0 cm TL macho/indeterminado; (Ref. 40637); 90.0 cm TL (female); common length : 50.0 cm TL macho/indeterminado; (Ref. ); peso máx. Publicado: 1.4 kg (Ref. 40637)

Depth range is reported at 55m-1200m in Ref. 9996. Found on the outer continental shelves and upper slopes. Feeds mainly on bottom invertebrates, including shrimps and cephalopods, but also on small pelagic bony fishes (lanternfishes) and other small elasmobranchs. Oviparous, with up to 13 eggs present in the oviducts at one time. Individuals from the Ionian Sea apparently reproduces from end of February to September and eggs are laid between 200 and 600 meters (Ref. 87978). Utilized fresh and dried-salted for human consumption, and for leather.

Estimates based on models

Preferred temperature (Ref. 123201): 4.4 - 14.4, mean 10.3 °C (based on 708 cells).

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

Bayesian length-weight: a=0.00269 (0.00227 - 0.00320), b=3.02 (2.97 - 3.07), in cm total length, based on LWR estimates for this species (Ref. 93245).

Nível Trófico (Ref. 69278): 4.2 ±0.3 se; based on diet studies.

Generation time: 2.6 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliência (Ref. 120179): Baixo, tempo mínimo de duplicação da população 4,5 - 14 anos (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (35 of 100).

Climate Vulnerability (Ref. 125649): Low to moderate vulnerability (33 of 100).

Categoria de preço (Ref. 80766): High.
