Bony fish (Osteichthyes) are distinguished from other fish species that have a cartilaginous skeleton (Chondrichthyesâsharks, rays and chimaeras, for example) by the presence of true boneâa mixture of calcium phosphates and carbonatesâin their skeletons.
Bony fishes can swim forward and backward.   Gills:   Both cartilaginous and bony fish have gill slits but the bony fish also have gill covers (an operculum).   Reproduction:   In the Chondrichthyes the males have claspers which assist in copulation. Fertilisation is internal-almost unique among fish. Scales:   Cartilaginous fish have large scales called placoid scales. These have a bone like base embedded in the skin and a backward projecting enamel covered dentine spine. The whole thing has a central pulp cavity (rather like the structure of teeth). The epidermis and dermis form placoid scales.
