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).

संक्षिप्त वर्णन
पहचान कुंजी | आकृति विज्ञान | मौरफोमैटरिक्स

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).
