Blue World,the Amazing Comeback Of Gray Seals + Shark Performanc

Gray seals look like cute swimming puppy dogs, and their story of recovery from the brink of extinction is one of the best examples of conservation in history. Blue World joins a team of seal researchers on Cape Cod, and dives with these adorable pups of the sea to tell their story. Then we travel to the town of Oslob in the Philippines, where the local people have switched from hunting whale sharks to getting them to perform for tourists, proving that sharks are worth more alive than dead.
