Amphibians are vertebrates, meaning they have a backbone. The skeletal system is mostly made up of bone, but also contains some smaller portions of cartilage. Not all vertebrates have bone skeletons, Chondrichthyes (sharks, rays etc.) have skeletons made up entirely of cartilage. Amphibians however do not.
The skeletons of lampreys and hagfishes are made of cartilage rather than bone. This cartilaginous skeleton provides structure and support to their bodies without the need for true bones.
The skeleton of jawless fish, such as lampreys and hagfish, is primarily made of cartilage rather than bone. Cartilage is a flexible and lightweight tissue that provides structure and support to these fish without the need for heavy bones.
