Lake Baikal
The oldest and deepest lake on Earth/Water
Lake Baikal in Siberia is roughly 25 million years old, making it the most ancient lake on the planet. It holds about 20% of the world's unfrozen surface freshwater -- more than all the North American Great Lakes combined. Its extreme depth and isolation have produced over 2,500 species found nowhere else, including the nerpa, the only exclusively freshwater seal.
