About 18 times greater than seawater, Antarctica’s Don Juan Pond is the saltiest body on Earth. The small, shallow basin is technically a lake although popularly referred to as a pond. Its few thousand square meters can only accommodate extremophiles like bacteria and fungi thanks to its hypersalinity. Located in Antarctica’s McMurdo Dry Valleys (the largest ice-free region on the continent), you’ll find many of the world’s saltiest lakes there.
