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); punctulatus: Diminutive of punctum (L.), spot, i.e., having tiny spots, referring to small black spots often present on body (See ETYFish).
