Tamaño / Peso / Age

Maturity: L_m ? range ? - ? cm
Max length : 300 cm TL macho / no sexado; (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 Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

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=0.00363 (0.00143 - 0.00920), b=3.09 (2.87 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.5 ±0.37 se; based on food items.

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

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

Price category (Ref. 80766): Low.
