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); canis: Latin for dog (sharks were known as “sea dogs” and “dog-fishe” among mariners until the late 16th century, because of their ferocious pack-like feeding behavior) (See ETYFish).

marino; salobre demersal; oceanodromo (Ref. 51243); rango de profundidad 0 - 800 m (Ref. 55584), usually 18 - 200 m (Ref. 55309). Subtropical; 46°N - 44°S, 98°W - 31°W
Western Atlantic: Massachusetts to Florida (USA), northern and western Gulf of Mexico, Venezuela, Cuba, Jamaica, Barbados, Bermuda, Bahamas; southern Brazil to northern Argentina; also western Gulf of Mexico and Antilles (Ref. 26938). Northwest Atlantic: Canada (Ref. 5951). Allopatric with Mustelus mustelus and sympatric with Mustelus norrisi. One of the two new allopatric species of canis- norrisi-like smooth-hounds in this region is often confused with this species (Ref. 244). The subspecies Mustelus canis insularis, occurring at several Caribbean islands, was identified by Heemstra (Ref. 27770).

Madurez: Lm 99.8, range 95 - 100 cm
Max length : 150 cm TL macho / no sexado; (Ref. 244); common length : 100.0 cm TL macho / no sexado; (Ref. 6077); peso máximo publicado: 12.2 kg (Ref. 40637)
A small, slim shark. Well-serrated dorsal fins, second nearly as large as first (Ref. 26938).
Body shape (shape guide): elongated.
Found on continental and insular shelves and upper slopes, ranging from shallow inshore waters and the intertidal to 200 m, occasionally down to 579 m (Ref. 244). Occasionally found in freshwater. It is doubtful that this species can live in fresh water for an extended period of time (Ref. 244). Active swimmer and bottom feeder (Ref. 27549). Swims in packs or schools (Ref. 27549). Feeds on large crustaceans, mainly crabs, but also heavily on lobsters (Homarus) (Ref. 244). Probably non-territorial. Off the Atlantic coast of the USA, this species is migratory (Ref. 244). Viviparous (with a yolk-sac placenta), with 4 to 20 young in a litter. Longevity given as 7 years (Ref. 775) but appears too low. Utilized fresh, dried-salted, and smoked (Ref. 9987).
