A common inshore to offshore shark found on the continental shelf. Oviparous (Ref. 50449). Dental sexual dimorphism exists, with adult males having teeth at least twice as high as adult females as well as much longer and narrower mouths.
一種常見的沿海地區到外海的鯊魚發現於大陸棚了。 卵生的.(參考文獻 50449) 牙齒的性同種二形存在, 雄性成魚的牙齒至少兩倍高於雌性成魚以及嘴巴較長且較窄。
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Sexual dimorphism is evident in dentition of male species (Ref. 49562). Males have longer teeth with fewer cusps than females (Ref. 51093) to make 'courtship biting' more effective (Ref. 49562).東南太平洋與西南大西洋: 智利中部到麥哲倫海峽與阿根廷。
