Etymology: Schroederichthys: In honor of American ichthyologist William C. Schroeder (1895-1977), Woods Hole Oceanographic Institution, for his pioneering work (with Henry B. Bigelow) on cartilaginous fishes; ichthyos (Gr.), fish (See ETYFish); bivius: bi-, from bis (L.), two; via (L.), way or passage, etymology not explained, perhaps referring to double-valved nostrils, with incurrent and excurrent apertures (See ETYFish).
Eponymy: William Charles Schroeder (1894–1977) was an American oceanographer and ichthyologist. [...] (Ref. 128868), visit book page.

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.
一种常见的沿海地区到外海的鲨鱼发现于大陆架了。 卵生的.(参考文献 50449) 牙齿的性同种二形存在, 雄性成鱼的牙齿至少两倍高于雌性成鱼以及嘴巴较长且较窄。

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。
