Elasmobranchii (sharks and rays) > Carcharhiniformes
(Ground sharks) > Pentanchidae
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); kampae: In honor of Elizabeth Kampa Boden (1922-1986), Scripps Institution of Oceanography, chief scientist aboard the research vessel Argos, from which holotype was collected. (See ETYFish).
