Whale

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

The Public Broadcasting Service, known for airing pro-evolution shows, admitted, "The evolution of whales has been a mystery."

One prominent story about a whale is that of Jonas:

For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth. - Matthew 12:40.
