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).
Cycle de vie et comportement reproducteur
Maturité | Reproduction | Frai | Œufs | Fécondité | Larves
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).
