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.

Краткое описание
определительные ключи | морфология | морфометрия
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.
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).
