Acclaimed wildlife scientist Vanessa Pirotta has been mugged by whales, touched by a baby whale and covered in whale snot. In Humpback Highway, Pirotta dives beneath the surface to reveal the mysterious world of humpback whales from their life cycle and the challenges humans present to these marine giants to why whale snot and poo are important for us and the ocean. Plus the cutting-edge new technologies (including tagging whales so that they communicate with satellites) that allow us to see where they swim, listen to them talk and even spy on them underwater.
