Chondrichthyes

a class of the phylum Chordata containing the cartilaginous fish, sharks, rays and chimaeras. In some classifications, the term is synonymous with ELASMOBRANCHII. They are the lowest vertebrates with complete and separate vertebrae, moveable jaws and paired appendages. All are predators and virtually all are marine. They are characterized by the absence of true bone and the presence of CLASPERS (1) in males, and DENTICLES.
