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).

Maturité: Lm 90.9, range 79 - 100 cm
Max length : 125 cm TL mâle / non sexé; (Ref. 9072); 151.0 cm TL (female); common length : 85.0 cm TL mâle / non sexé; (Ref. 9258)
Found on the insular shelves, often close inshore (Ref. 244). Feeds on crustaceans, especially crabs (Ref. 244). Ovoviviparous (Ref. 50449). Makes seasonal inshore-offshore movements (Ref. 244). Makes extensive coastal migrations, with one tagged female moving at least 1160 km (Ref. 54100). Forms schools separated by size and sex (Ref. 244). Utilized fresh for human consumption (Ref. 244).
