The blue whale - over 30 metres long and as heavy as 40 elephants - is the largest animal in the world and could only survive in the ocean. Yet whales, like other mammals, once lived on land, and weren't always so big. This program explains why these smart, social animals first took to water, and how they have adapted to aquatic life despite retaining the most basic need of land mammals: to exchange air through the lungs.
