Actinopterygii
These are one of the major groups of bony fishes - the ray-fins that have fins that internally supported by flexible rays, in contrast to the Sarcopterygii that have lobe-fins. Nearly all fishes in this group are telosts, about 21,000 species that became the dominant fishes by the end of the Cretaceous.
Unlike sharks, the skeletons of ray-finned fishes are made of bone rather than cartilage. Unlike lobefins, their fins radiate out from a point rather than radiating out from a point at the end of a stalk where the stalk and the radial bones make up the fin.
The teleosts also have symmetrical tails, thin scales, a swim bladder, highly menuverable fins, and jaws that are move, making them adapted for sucking as well as biting, as summarized by Moyle. page 75.
Older teleosts live in freshwater and newer ones are more marine, including deepwater and pelagic forms, so fishes radiated into marine environments.
