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); dorsalis: Latin for “of the back,” referring to “projection of the posterior angle of the first dorsal fin to the vertical of the origin of the ventrals”. (See ETYFish).
