Pupfish

Tiny pupfish are ther remnants of- and living clues to- Death Valley's once wetter past. For hundreds of thousands of years ending 10,000 years ago, Death Valley contained large lakes fed by abundant rainfall and meltwater from receding ice age glaciers in the Sierra Nevada. Climate change gradually dried up the valley lakes and forced most life- whether pupfish or human- to congregate near permanent water sources or to adapt to dry conditions. Since then desert pupfish ave survived, living in isolated-springs as warm as 90F and in streams whose water can be 5 times as salty as the ocean water. Rarest of the all, the Devils Hole pupfish is on the endangered species list. Further decreases in available water threaten its future. Death Valley offers us an opportunity to understand how vital fresh water is to our planet, which is a closed water system.
