A whale (cetacean) is a massive mammal that lives in the ocean. It relies on fresh air just like other mammals, and unlike fish. The whale is warm-blooded like animals, and unlike fish. But whales have many extraordinary features that are not like other mammals, including:
- they decide when to breathe, rather than breathing unconsciously
- they sleep 8 hours a day, yet need to be conscious to breathe
- they can communicate with each other by making remarkably loud noises
- these extraordinary noises can travel for miles under water
- the females nurse their calves while swimming underwater
- the nursing calves are somehow able to avoid taking in saltwater while nursing
- the males have a unique cooling system for their internal reproductive organs
- some have two blow-holes, but others only have one
- the blow-holes pass air above water, yet resist intense pressure underwater
- they have massive brains, much larger than the brains of other mammals
- Various fictional tales notwithstanding, remaining alive inside a whale for any length of time would be impossible due to lack of oxygen and the presence of strong acids.
