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);  ravidus: Latin for grayish, referring to its pale-gray dorsal coloration. (See ETYFish).
