The Actinopterygii, or ray-finned fish, are a class of fish within the group of bony fish (Osteichthyes). Unlike cartilaginous fish (Chondrichthyes), bony fishes posses a skeleton completly composed of bone. The ray-finned fish are not the only class within the Osteichthyes, the lobe-finned fish (Sarcopterygii) are also placed in this group.
