Size / Gewicht / Alter

Maturity: L_m ? range ? - 130 cm
Max length : 270 cm TL Männchen/unbestimmt; (Ref. 106604); max. veröff. Gewicht: 240.0 kg (Ref. 114953)

A benthic species mainly found near the coast in shallow bays and off river mouths. It is poorly known but probably feeds on bottom-dwelling crustaceans and fishes (Ref. 114953). Ovoviviparous (Ref. 50449).

Life cycle and mating behavior Geschlechtsreife | Fortpflanzung | Ablaichen | Eier | Fecundity | Larven

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

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5049 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00372 (0.00163 - 0.00845), b=3.11 (2.91 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.6 se; based on size and trophs of closest relatives

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).

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