Dolphins are mammals that live in the ocean. Mammals are different from fish, reptiles, or birds. As mammals, dolphins breathe oxygen, even though they live in water. Because it is a mammal, a dolphin mother gives birth to a live baby, unlike reptiles and birds, which lay eggs. A dolphin mother also feeds her baby milk like other mammals.
