Biologie     Fachlexikon (Englisch) (z.B. epibenthic)

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.

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. 82805):  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).
Trophic level (Ref. 69278):  3.8   ±0.4 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).
Verwundbarkeit (Ref. 59153):  Moderate to high vulnerability (47 of 100) .
