Brief Summary
provided by Ecomare
Smooth hounds are harmless ground sharks. They teeth aren't even sharp, but instead are flat crowned teeth. These teeth are great at finely grinding their food, such as crabs, shellfish and other fish, before swallowing. The number of smooth hounds in the North Sea has increased in the past thirty years, while other shark species have declined in the same period. Smooth hounds are named after their habit to gather in large groups, like a pack of dogs (or hounds).

Trophic Strategy
provided by Fishbase
Found on the continental shelves and uppermost slopes, from the intertidal region to at least 350 m depth (Ref. 244). Collected to depth of 624 m in the eastern Ionian Sea (Ref. 56504). Sometimes in midwater but prefers to swim near the bottom (Ref. 244). Feeds mainly on crustaceans, but also cephalopods and bony fishes (Ref. 244).

Common smooth-hound
provided by wikipedia EN
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.
