Jawless fishes were the first vertebrates to live on earth. As their name suggests, they have no jaws. Instead, they have mouths for scraping, stabbing and sucking food. Their skeletons are made of cartilage, not bone. Hagfishes and lampreys are the only jawless fishes that are still alive. They are usually scavengers, that live near the ocean floor. Some can also be parasites.
