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.
