Lake Pepto-Bismol

Those two dots are actually boats on Lake Retba in Senegal. The pink water, which made it look like the boats are floating on a Pepto-Bismol lake, got its color from the extremely high levels of salt.

Michael Danson, an expert in extremophile bacteria from Bath University, said: "The strawberry colour is produced by salt-loving organism Dunaliella salina.

"They produce a red pigment that absorbs and uses the energy of sunlight to create more energy, turning the water pink.

"Lakes like Retba and the Dead Sea, which have high salt concentrations, were once thought to be incompatible with life - hence the names. But they are very much alive."

Salt collectors can often be seen scouring the expanse to remove the valuable mineral - but first have to coat their skin with sheer butter.
