Mustelus canis is a species of shark commonly known as the smoothhound shark. It belongs to the family Triakidae and is predominantly found in coastal waters of the western Atlantic Ocean, ranging from Nova Scotia in Canada to the northern Gulf of Mexico. This medium-sized, slim-bodied shark typically measures around 4-5 feet in length and weighs approximately 30-40 pounds.
The smoothhound shark has distinctive features such as a long, slender snout, large eyes, and a broad mouth containing numerous small, sharp teeth. Its dorsal fin is set far back on its body, positioned closer to the tail than in most other sharks. The species exhibits a grayish-brown coloration on its upper body with a lighter shade underneath, aiding in camouflage against the ocean floor.
As a bottom-dwelling shark, Mustelus canis is primarily found in shallow inshore waters and estuaries, making it well-suited for a variety of habitats, including sandy or muddy bottoms. It is an opportunistic feeder, preying on small fishes, crustaceans, and cephalopods that reside in its foraging area.
Due to its commercial value, the smoothhound shark species is targeted by both recreational and commercial fishermen. It is highly valued for its meat, which is consumed fresh or frozen, as well as for its liver oil and fins. However, its population is considered stable and not currently at risk from overfishing.
In conclusion, Mustelus canis is a species of shark commonly known as the smoothhound shark, which inhabits coastal waters of the western Atlantic Ocean, has distinctive physical characteristics, and is a valuable resource for human consumption.
