Bony fish
Fish with skeletons of bone: the ray-finned and lobe-finned fish, which make up almost all living fish species.
Also: Osteichthyes
Bony fish have skeletons made largely of bone, a gill cover, the operculum, and usually a swim bladder or lungs. They include the ray-finned fish, which are almost every fish people know, and the lobe-finned fish, which are the coelacanths and lungfish, and, in the family tree, all land vertebrates. With more than 35,000 known species, bony fish are the largest group of vertebrates, outnumbering mammals, birds, reptiles and amphibians put together, and new species are named every year.
