Length at first maturity / Size / Vikt / Age

Maturity: L_m 48.0 range ? - ? cm
Max length : 250 cm WD hane/ej könsbestämd; (Ref. 30573)

Ovoviviparous (Ref. 50449). Caught often in demersal trawls, and occasionally by trammel net. Utilized for its meat, but of limited value due to its typically small size (Ref. 58048).

Life cycle and mating behavior Maturities | Reproduktion | Spawnings | Egg(s) | Fecundities | Larver

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). Distinct pairing with embrace (Ref. 205). Gives birth to litters of up to 7 pups; born at 24-26 cm WD (Ref. 58048).
