Most fish are covered in scales for protection. They vary in size, shape and structure and can range from strong and rigid to small or absent. The main types of scales include the cycloid scales, the ctenoid scales, the placoid scales and the ganoid scales.

There are three general groups. The first group is jawless fish. They only contain lampreys and hagfishes. The second group is cartilaginous fish, which includes sharks, rays, and their relatives. The last group is bony fish, and they contain every other kind of fish- tuna, clownfish, anglerfish, whatever.
Actinopterygii or the ray finned bony fishes are the dominant class of not only fish, but of vertebrates with an estimated 30000 species. Since you didn't ask specifically I've given you a pretty general answer. Actinopterygii contain many orders and classes of fish.
Both jawless fish and cartilaginous fish have skeletons composed of cartilage and distinct brains. Also, some cartilaginous fish don't have scales, and all jawless fish don't have scales. Cartilaginous fish, however, have jaws, paired appendages, and a kind of vertebrae. Jawless fish do not have jaws, paired appendages, and often are without vertebrae.
