Max length : 114 cm TL male/unsexed; (Ref. 111131)

Biology     Glossary (e.g. epibenthic)

Mainly coastal, benthic species with unknown biology (Ref. 114953). May reach 170 cm TL (Ref. 12951). Ovoviviparous (Ref. 50449).

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

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5020 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00229 (0.00137 - 0.00383), b=3.11 (2.97 - 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) 		Moderate to high vulnerability (54 of 100). 🛈
Climate Vulnerability
(Ref. 125649) 		High to very high vulnerability (73 of 100). 🛈
