Lake Retba in Senegal is a salt lake which is naturally bright pink like strawberry milkshake.

The colour comes from microbes which use a type of photosynthesis which evolved separately to the kind that plants use. The chemical machinery those microbes use is rhodopsin – the same stuff which is found in your retinas, allowing you to see.

Gah. Had to delete and redraft this to fix a silly mistake. That's what I get for trying to write stuff while half asleep on the bus to campus.

Everything about these pink lakes is so fascinating to me. I may have fallen down a Wikipedia hole one afternoon, which I proceeded to stay in all night long!
