Summary

Description

The nurse hound Scyliorhinus stellaris is a large catshark that can reach up to 1.6 m in length. It is slender but fairly stocky in build. It has two dorsal fins, located towards the rear half of the body. It has an anal fin unlike members of the dogfish family. Scyliorhinus stellaris is easily recognised by the large and small black spots (and sometimes white spots) on its creamy brown back. The underside is white.
