Cartilaginous fish do not have true bones and belong to a the class Chondrichthyes. Sharks, rays and skates are the best-known of this class. True bony fish belong to the class Osteichthyes. One of the major differences is that the members of the class Chondrichthyes lack the ability to pump water past their gill plates, so they must constantly be on the move or in a fast moving current when they are at rest.
Jawless fish are cartilaginous, but they do not have jaws. Class Chondrichthyes, which contains most cartilaginous fish, like sharks, have powerful jaws.
