Pentanchidae (Deepwater catsharks)
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); garricki: In honor of J.A.F. (Jack) Garrick (1928-2018), “pioneer” New Zealand shark taxonomist and biologist, the first to recognize this genus from New Zealand waters; he also “generously” shared his notes on this species with the authors. (See ETYFish).
