Life in hell - survivors of salt and acid

Some species are perfectly adapted to live in conditions that would be lethal to the vast majority of other organisms. Scientists have baptized them extremophiles, that love extreme conditions.

They are found mainly in the most uninhabitable places and especially in large saline lakes and rivers acids: lake Rose in Senegal, salt swamps in France, lake Natron in Kenya, Mono and Owens lakes in the United States and acid river in Spain.
