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); australis: Latin for southern, referring to its distribution in the southern hemisphere around Australia (See ETYFish).
Eponymy: Pinocchio is a fictional character created by Carlo Collodi in his childrens’ novel: The Adventures of Pinocchio (1883). [...] (Ref. 128868), visit book page.
