Planet Earth II S01 E01
But there's always a price to pay for island life. In the Galapagos Islands, young marine iguanas must flee the onslaught of deadly gonzo snakes as they hatch from the sand. On the sub-Antarctic island of Zavodovsky, life is even more extreme. Every day, one and a half million penguins risk being smashed against the rocks by ferocious waves as they try to get on and off the island.
