Life cycle and mating behavior
成熟度 | 繁殖 | 產卵場 | 卵 | 孕卵數 | 仔魚
Eggs are sometimes fertilized internally by accident via close apposition of gonopores in otherwise oviparous fishes and may be retained within the female's body and complete some of the early stages of embryonic development. Embryos feed solely on yolk (Ref. 50449). Bears up to 12 young (Ref. 5578), size at birth 11-12 cm (Ref. 5510).東大西洋: 摩洛哥南部到那米比亞。
