DEVILS HOLE – SURVIVAL IN A DESERT CAVE

Looking into the south end of Devils Hole, a collapsed cavern roof, home to one of the rarest vertebrate species in the world – the Devils Hole pupfish.

Today’s post concentrates on some of the unique species of life to be found in the various oasis springs found 1-2 hours west of Vegas among the desert basin area of the Amargosa Valley. In some of these springs, various species of pupfish live, their only home in the world. These fish include some of the rarest found today. The fish, like other animals and plants found around the oases, are survivors. One has to, in order to survive the climate and environment in which they call “home”.
