(Hainan Adventure With Nigel Marven/2012) Presenter Nigel Marven follows in the footsteps of his hero, John Whitehead, an English naturalist and explorer who visited Hainan in 1899. On this island, China's only tropical province, Nigel tracks down animals first discovered by and named after Whitehead. He swims with five-metre whale sharks in the South China Sea, explores fabulous coastal reefs, uncovers remarkable turtles and frogs, and finds an abandoned house with an unbelievable 10,000 fruit bats hidden in the roof! He also investigates the story of the world's rarest primate, the Hainan gibbon - less than twenty of these amazing apes remain.
