No, a shark is not a mammal; it is classified as a fish.

Sharks are not mammals because

  • They have no hair or fur
  • They do not feed their young on milk
  • They do not breath air

Sharks are all cartilaginous (they have no ossified bones). They all obtain the oxygen they need using gills perfused by water. They all reproduce using eggs (some species retain the eggs and produce young ovoviviparously) and do not care for the young at all once hatched. They also have no hair but please note that some species of shark (the great white) seem to be partially warm blooded but that does not make them mammals.

Chondrichthyes (pronounced /kɒnˈdrɪkθi.iːz/) or cartilaginous fishes are jawed fish with paired fins, paired nares, scales, two-chambered hearts, and skeletons made of cartilage rather than bone. They are divided into two subclasses: Elasmobranchii (sharks, rays and skates) and Holocephali (chimaera, sometimes called ghost sharks, which are sometimes separated into their own class).
