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); lenticulatus: Latin for freckled, referring to peppering of white spots on upper sides. (See ETYFish).
Environment: milieu / climate zone / depth range / distribution range
