| Descripción del ciclo vital y del comportamiento de acoplamiento | Ovoviviparous, produce 7-25 pups/litter (Ref. 58085), 13.0 +/- 1.9 pups in the Canary Is (Ref. 107713) with litter number increasing with female size. Gestation period lasts for 8-10 months (born Dec-Feb in Mediterranean, July in England) (Ref. 58085), and +/- 6 months in the Canary Is (Ref. 107713). Size at birth ranges from 24-30 cm TL (Ref. 58085). Embryos feed solely on yolk (Ref. 50449). Full term embryos weighed 189-200 g; no egg capsules found around ova or embryos (Ref. 107715). A biannual reproductive cycle is likely the case for this species (Ref. 32746), triannual cycle in the Canary Is (Ref. 107713). |
