Mustelus canis, commonly known as the smooth dogfish, is a species of shark found primarily along the Atlantic coast of North America. It typically inhabits shallow waters, such as bays and estuaries, and can be recognized by its slender body and smooth skin. This species can grow up to 1.5 meters in length and is characterized by its long, pointed snout. The smooth dogfish primarily feeds on small fish, crustaceans, and mollusks. It is known for its docile nature and is often caught by recreational fishermen. Although not considered endangered, Mustelus canis faces threats from overfishing and habitat loss.
