Curious Baby Humpback Whale 'Dances' With Mum and Divers

This humpback whale and its calf were found playing off the coast of Tonga. Mother whales leave Antarctica, where they feed, for warmer waters, where they will give birth.

Newborn humpback whales weigh about 1.5 tons. A fully grown whale can weigh over 40 tons. Baby humpbacks will drink 50 gallons of milk and gain up to 100 pounds every day. This calf certainly was a curious one.
