Whale is placed in mammalia as it cannot breath the oxygen in water and it needs the oxygen mixed in air. It is not completed adapted to aquatic life like fish. As you know, they need to come up after a certain time for oxygen. Their mode of reproduction is vivaparous. (Not by eggs but by internal fertilization)
