c. Marine bony fish
All bony fish have segmented fin rays that are derived from their epidermis and sutures in their neurocranium. Both bony fish and cartilaginous fish have gills for breathing, but the gills of bony fish are protected by a hard, bony plate. Bony fish may also have prominent rays, or spines, in their fins; this characteristic is known as a "operculum".
Bony fish, in contrast to cartilaginous fish, have swim or gas bladders to control their buoyancy. On the other hand, cartilaginous fish require constant swimming to maintain buoyancy.
