Jawless fish, such as lampreys and hagfish, are unique because they lack jaws and paired fins, which distinguishes them from other vertebrates. Instead of jaws, they have a round, sucker-like mouth that allows them to feed by attaching to their prey or scavenging. They also possess a notochord, a primitive backbone structure, and their bodies are often covered in slime rather than scales. Their evolutionary adaptations provide insights into the early stages of vertebrate development.
