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); whitneyi: In honor of American fisheries biologist Richard R. Whitney (1927-2011), for his teachings and guidance during the author’s study of sharks. (See ETYFish).
