Bony fish or Teleosts have something called a swim bladder that can be filled with gas to give them neutral buoyancy in the water. Sharks and rays, (Chondrichthyes) are cartilaginous fish do not have swim bladders and 'fly' through the water using the lift they gain from their large pectoral fins and asymmetrical heteroceral tail. Like an aeroplane, if they stop moving they lose altitude and sink.
