Bony fish are divided into two groups, the lobe-finned fish, known mostly from fossils, and the vastly more numerous ray-finned fish. By examining their ear bones, scientists know that coelocanths are long-lived with some living as long as 80 to 100 years. Fish swim bladder in spirit. Many scientists believe that the unique characteristics of the coelacanth represent an early step in the evolution of fish to terrestrial four-legged animals like amphibians. There are three groups of lobe-finned fish: Actinistia (coelacanths), Dipnoi (lungfish) and Tetrapodomorpha (these guys are the ones that evolved into tetrapods - for example, the famous Tiktaalik.)

Actinopterygii ( (Figure) a ), the ray-finned fishes, include many familiar fishestuna, bass, trout, and salmon among othersand represent about half of all vertebrate species. They are the sister group to the ray-finned fishes (Actinopterygii), together forming the bony fishes (Osteichthyes). This list may not reflect recent changes . Exocoetus whose body is covered with bony cycloid scales. Because this non-fish lineage is nested within a bunch of fish on the tree of life, the fish do not form a clade.
