The lake is home to a genus of brilliant red algae called Arthrospira, which loves salty, alkaline water. First, the lake has a distinctive, bright red color, and it gets that from a flourishing community of algae. Because of that, it's hard to imagine that anything can live in this lake. Any animal corpses unfortunate enough to land in the water end up mummified in a coat of minerals, and touching it is seriously painful for humans. The lake's temperature has been known to hit sixty (60) degrees Celsius. Depending on the conditions, its pH can be higher than 10 - that's a thousand times more basic than pure water. The water is alkaline - sometimes very alkaline. Tanzania's Lake Natron isn't exactly a pleasant place for a swim. Looking for SciShow elsewhere on the internet?

It's called SciShow Tangents. But some creatures have evolved amazing adaptations that help them survive and thrive in this alkaline lake.

With its caustic red waters, Lake Natron doesn’t seem like the ideal place to call home.
