Etymology: Scymnodalatias: scymno-, referring to previous placement in Scymnodon; dalatias, referring to lack of dorsal spines like most sharks in the family Dalatiidae (sometimes included within Somniosidae) (See ETYFish); garricki: In honor of J.A.F. (Jack) Garrick (1928-2018), New Zealand shark biologist, who proposed Scymnodalatias in 1956 [senior author’s name also seen as Kukuyev] (See ETYFish).
Eponymy: Dr John Andrew Frank (Jack) Garrick (1928–2018) was a New Zealand ichthyologist with a specialization in elasmobranchs. [...] (Ref. 128868), visit book page.
