Etymology: Apristurus: a-, Latin privative, i.e., without; pristis, from pristes (Gr.), sawyer (but here meaning saw); oura (Gr.), tail, referring to absence of saw-toothed crest of enlarged dermal denticles along upper edge of caudal fin as found in the closely related Pristiurus (=Galeus). (See ETYFish); riveri: In honor of biologist-anthropologist Luis Hugo Howell-Rivero (1899-1986), for his contributions to Cuban ichthyology (this shark described from the north coast of Cuba). (See ETYFish).

Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔鱼
Oviparous, paired eggs are laid. Embryos feed solely on yolk (Ref. 50449). Sexual dimorphism is evident in dentition of males (Ref. 49562). Males have longer teeth with fewer cusps (Ref. 51093) to make 'courtship biting' more effective (Ref. 49562).中西大西洋: 古巴，墨西哥灣北部與巴拿馬。
