Primarily benthic (Ref. 114953). Occurs mainly in the marine environment, but also enters the lower reaches of rivers. Ovoviviparous (Ref. 50449). Males mature by 68 cm TL; born at ca. 20 cm TL. Females produces litters up to 6 pups (Ref. 114953). Minimum depth range from Ref. 121775.

Levenscyclus en paargedrag Maturiteit | Voortplanting | Paaien | Eieren | Fecunditeit | 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

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00178 (0.00118 - 0.00267), b=3.10 (2.98 - 3.22), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.7 ±0.4 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): laag, minimale populatieverdubbelingstijd 4,5-14 jaar (Fec assumed to be <100).

Fishing Vulnerability (Ref. 59153): High vulnerability (56 of 100).
