How the world's rarest fish survives in Death Valley

In Death Valley National Park, in the most unlikely place imaginable, one of the rarest fish on earth makes its home in what amounts to a flooded cave. Every time there's an earthquake anywhere on earth, their tiny world shakes violently. The water is so hot that they're the only species of fish that can tolerate it.

We'll take you to Death Valley National Park to introduce you to these special fish, the legal battle they sparked that changed the entire American west, and the people working tirelessly to save this tiny, endangered species.
