Siberia Lake Baikal

This is Lake Baikal. This record breaking lake holds twenty percent of the Earth’s fresh water – as much as all five of America’s Great Lakes combined. But, with a water temperature rarely rising above eight degrees Celsius it’s not as inviting as it looks. But that’s okay for the residents, the only freshwater seals in the world: the Baikal seals.
