The Blue Realm - Humpbacks: From Tonga to Antarctica
Singing louder than any animal on earth, humpback whales are famous for their haunting songs and jaw-dropping acrobatics. They were hunted to the brink of extinction until a moratorium on killing them was implemented in the 1960s. But after finally rebounding in numbers, whaling nations are exploring ways to re-open the hunt. In Antarctica, Japan is targeting minke, fin, and now... humpbacks. The tiny island nation of Tonga in the remote South Pacific is a haven for the magnificent mammals.
