It is a mammal because of the blowhole on it's head. Amphibians do not have blowholes. Even though dolphins are aquatic they are mammals because they breathe air. Dolphins cannot breathe underwater or they will drown. Mothers help newborn dolphins to the surface so they can breathe. Everything that is aquatic or breathes air ONLY is a mammal.
