Biology     Glossary (e.g. epibenthic)

Benthic in shallow waters over sandy bottoms (Ref. 9262). Ovoviviparous (Ref. 50449). Produces litters of 1-6 pups. Females mature at ca. 48 cm TL, males at ca. 51 cm TL; born at 19 cm TL (Ref. 114953).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

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): 26.6 - 29.1, mean 28.3 °C (based on 115 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00182 (0.00117 - 0.00283), b=3.12 (2.99 - 3.25), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.6   ±0.5 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  High to very high vulnerability (71 of 100).
