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); stenseni: In honor of Danish geologist and anatomist Niels Stensen (1638-1686, also known as Nicolas Steno), for “important studies of elasmobranch anatomy, which, because of their scientific accuracy, were influential in the beginnings of elasmobranch systematics in the pre-Linnaean period and later, even to the time of the appearance of Müller and Henle’s ‘Plagiostomia’ in 1841” (See ETYFish).
Eponymy: Dr Neils Stensen (variously rendered Nicolas Steno, Nicolaus Stenonis or Nicolaus Stenonius) (1638–1686) was a Danish geologist, anatomist and author. [...] (Ref. 128868), visit book page.
