(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.
