Yes whales do have belly-buttons. Whales are mammals and to be classified as such they need to fulfill certain criteria. They breathe air, have hair, give birth to live young and nourish their young with milk. When a whale is born it is still attached to the cow (mother) by the umbilical cord which then needs to be detached (exactly how this is done is not fully known). leaving behind a belly button or scientifically the 'umbilicus'.
