Whales are the largest animals on Earth and they live in every ocean. The massive mammals range from the 600-pound dwarf sperm whale to the colossal blue whale, which can weigh more than 200 tons and stretch up to 100 feet long—almost as long as a professional basketball court. Just like us, they breathe air, have hair, are warm-blooded, give birth to live young, and feed their young milk. Whales are unique, beautiful, graceful and mysterious; they nurture, form friendships, innovate, grieve, play, sing and cooperate with one another. Whales are beautiful animals, they're elegant and strong. Whales are gentle creatures that need protecting. Whales have a big heart, literally and figuratively. They have been known to adopt dolphins when they are abandoned from their own pods.
