板鳃亚纲 (鲨鱼与 鱼) (sharks and rays) >

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); yangi: In honor of Lei Yang, College of Charleston (Charleston, South Carolina, USA), whose molecular phylogenetic work on sharks and rays has improved our understanding of their alpha taxonomy and phylogenetic relationships. (See ETYFish).
