All life on Earth depends on water. But what if there’s not enough water in a place, such as in a desert? Or what if the water is supersalty, superhot, or superoily?
Extreme water conditions call for extreme methods of survival. Some animals have tricks or traits to cope with extreme water conditions. If a water hole dries up, a lungfish can survive because it has lungs (organs for breathing oxygen in air) in addition to gills (organs for breathing oxygen in water).
Anywhere that water extremes exist, so do some of the toughest life-forms on Earth!
