What are the differences between jaw less fish and cartilaginous fish?
Jawless fish and cartilaginous fish have cartilaginous skeletons, and bony fish have skeletons made from bone. Cartilaginous fish and bony fish both have jaws, paired appendages, and whole vertebrae, and jawless fish lack jaws, paired appendages, and often are without whole vertebrae. Cartilaginous fish can have scales or be naked, jawless fish are naked, and bony fish have scales. Bony fish have swim bladders, and cartilaginous fish do not. Jawless fish, cartilaginous fish, and bony fish all have fins, gills, and dorsal nerve cords that lead to a distinct brain. They all also have postanal tails and notochords.

What would be the relative ages of fossils found of a fish with a jaw a jaw-less fish and a fish with leg-like fins?
In the evolutionary timeline, jawless fish would be the oldest fossils, as they represent some of the earliest vertebrates. Fish with jaws evolved later, marking a significant advancement in fish evolution. Fish with leg-like fins, such as those leading to the first tetrapods, would be the most recent, as they represent a transition from aquatic to terrestrial life. Thus, the relative ages from oldest to youngest would be jawless fish, fish with jaws, and fish with leg-like fins.

What makes a jaw less fish unique?
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.
