Etymology: Mustelus: Latin for weasel, an ancient name for sharks, possibly referring to the pointed snouts, swift movements and/or rapacious feeding behavior of smaller predatory sharks [strictly not tautonymous with Squalus mustelus Linnaeus 1758 since type was designated by the ICZN] (See ETYFish); norrisi: In honor of American zoologist Harry Waldo Norris (1862-1946), Grinnell College (Iowa), who studied the cranial nerves of the Spiny Dogfish Squalus acanthias (See ETYFish).
Eponymy: Dr Harry Waldo Norris (1862–1946) was a zoologist and anatomist who was Professor of Biology and Zoology and Curator of the Museum at Grinnell College, Iowa (1891–1931) and was Research Professor of Zoology (1931–1941), retiring as Emeritus [...] (Ref. 128868), visit book page.
