Cartilaginous fish are classified as which group?

Explanation:
Cartilaginous fish are grouped together based on a skeleton made primarily of cartilage rather than bone. In vertebrate classification, this sets them apart from bony fish, which have skeletons of bone (the Osteichthyes), and from jawless fish, which lack true jaws (the Agnatha). Amphibia refers to a different animal group altogether, not fish. Sharks, rays, and chimaeras are classic examples of the cartilaginous fish, so the best classification term for them is Chondrichthyes.
