(C) Osteichthyes,commonly known as bony fishes,possess an endoskeleton made of bone. Their skin is covered with cycloid or ctenoid scales,not placoid scales (which are characteristic of Chondrichthyes). $A$ key diagnostic feature of bony fishes is that their caudal fin is typically homocercal,meaning the two lobes are equal in size. In contrast,Chondrichthyes (cartilaginous fishes) have a heterocercal caudal fin.
