∙ 14y ago
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.

∙ 14y agoJawless fish do not have paired appendages, but cartilaginous fish do. Cartilaginous fish can also have placoid scales or be naked, but jawless fish are always naked. Cartilaginous fish have strong jaws, but jawless fish have no jaw at all, hence their name. Jawless fish often do not have vertebrae, but cartilaginous fish always have vertebrae. Cartilaginous fish and jawless fish both, however, have gills, postanal tails, dorsal nerve cords that lead to a distinct brain, and notochords.

Cartilaginous joints are connected entirely by cartilage (fibrocartilage or hyaline).[1] Cartilaginous joints allow more movement between bones than a fibrous joint but less than the highly mobile synovial joint. An example would be the joint between the manubrium and the sternum. Cartilaginous joints also form the growth regions of immature long bones and the intervertebral discs of the spinal column.
