The common smooth-hound (Mustelus mustelus) is a houndshark of the family Triakidae. It is found in the eastern Atlantic Ocean from the British Isles to South Africa , and in the Mediterranean Sea, Madeira, and the Canary Islands at depths ranging from 5 to 625 m (although they usually stay at depths of 5-50m). While they can grow to 200 cm, their usual maximum size is 150 cm. They commonly grow to 100–120 cm with a birth length around 35 cm. The reproduction of commons smooth-hounds is viviparous.
Morphology and behavior
The common smooth-hound has a grey-brown back and is white on its underneath. It is often confused with the starry smooth-hound, which has white spots on its back. The starry smooth-hound can often have faded spots that leads to misidentification. Another shark with which it is often confused is the tope shark, although the common smooth-hound has a larger second dorsal fin. The common smooth-hound has two dorsal fins, an anal fin, a pair of pectoral fins, a pair of pelvic fins, and a heterocercal tail. All of these fins help stabilise the shark, but in males, the pelvic fins are modified to form claspers.
Like other smooth-hound sharks, the common smooth-hound aggregates in large numbers, like a pack of dogs, so they are called hounds.
