One order of this taxonomic class of animals is known as Polypteriformes and can only be found in Africa. That order is found in the subclass Sarcopterygii, and an infraclass of this group is known as Teleostei and has the most members. Primitive members have ganoid scales, while more modern ones can exhibit cycloid scales that have annuli which can be used to predict age. An operculum covering the gills is present in all these organisms as well as a swim bladder. For 10 points, identify this class of vertebrates separated into 'fleshy-finned' and ‘ray-finned,' and whose main difference with Chondrichthyes is their bony skeleton.
