RENO, Nev. (AP) -- For 10,000 years, a tiny iridescent blue fish has lived in the depths of a cavern in Nevada's desert, but a new study says climate change and warming waters --and its lack of mobility-- are threatening the pupfish and decreasing its numbers.
Scientists anticipate that as Earth continues to warm, fish and wildlife will migrate away from the equator or seek higher ground for a cooler habitat closer to what they've always known.
Mark Hausner, a hydrologist at the Desert Research Institute in Las Vegas, says it's a matter of "migrate, adapt or die."
But a new study he co-authored, "Life in a Fishbowl," says the Devils Hole pupfish has no way to escape the isolated canyon on the edge of Death Valley National Park.
