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); schmitti: In honor of American biologist Waldo L. Schmitt (1887-1977), curator of marine invertebrates at the U.S. National Museum, who collected holotype. (See ETYFish).
