Biologia     Glossário (ex. epibenthic)

A benthic species often found in very shallow water near the coast and offshore on the continental shelf (Ref. 9909, Ref.114953). Feed on small mollusks and bony fishes (Ref. 12951). Ovoviviparous (Ref. 50449). Produces up to 10 pups a litter, mainly from May to October (in the Red Sea region) (Ref. 114953). Size at least 171 cm TL. Males matures at ca. 83 cm TL, birth size at ca. 29 cm TL (Ref.114953). Utilized where it occurs but information lacking (Ref. 9909).

Life cycle and mating behavior Maturidade | Reprodução | Desova | Ovos | Fecundidade | 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. 115969): 24.7 - 29.1, mean 27.9 (based on 1002 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00138 - 0.01094), b=3.05 (2.82 - 3.28), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nível Trófico (Ref. 69278):  4.1   ±0.67 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).
