Life cycle and mating behavior 成熟度 | 繁殖 | 產卵場 | | 孕卵數 | 仔魚

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). Brood consists of 1-3 neonates and grow to about 40 cm DW in spring-summer (Ref. 38396).東太平洋: 南加州灣到哥倫比亞與加拉巴哥群島。
