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); sherwoodi: In honor of C. W. Sherwood, who discovered the shark washed up on a beach in Canterbury, New Zealand, and presented it to the local museum (See ETYFish).
Eponymy: C W Sherwood discovered the holotype lying washed up on the beach at New Brighton, New Zealand (1920) and presented it to the Canterbury Museum. Nothing further was recorded. (Ref. 128868), visit book page.
