Hybodus was a small shark that grew up to 2 meters in length and was thought to have been an opportunistic predator. It had a streamline shape which would have made it adept at hunting down fast prey as well as two different types of teeth sharp cutting teeth for catching prey and flatter grinding teeth for crushing. It is believed that this combination is the key to Hybodus' success.
