Tamanho / Peso / Idade

Maturity: L_m ? range ? - ? cm
Max length : 300 cm TL macho/indeterminado; (Ref. 58048)

Found inshore (Ref. 9909) and offshore (Ref. 58784). A carnivorous fish that feeds on large shellfishes (Ref. 58784). Ovoviviparous (Ref. 50449). Biology little known (Ref. 9909). Caught occasionally by demersal tangle net fisheries operating throughout the area. Utilized for its meat, find (both very high value), skin and cartilage (Ref.58048). Marketed fresh and probably dried-salted (Ref. 9909).

Life cycle and mating behavior Maturities | Reprodução | Spawnings | Egg(s) | Fecundities | Larvas

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449).

Estimates based on models

Preferred temperature (Ref. 123201): 24.8 - 29.1, mean 28.1 °C (based on 1958 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00145 - 0.00950), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.5 ±0.37 se; based on food items.

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

Fishing Vulnerability (Ref. 59153): Very high vulnerability (90 of 100).

Categoria de preço (Ref. 80766): Low.
