Kept under lock and key, the Devils Hole pupfish (Cyprinodon diabolis) has teetered on the brink of extinction since it made the federal list of endangered species in 1967. In April, biologists announced that Ash Meadows pupfish had laid eggs in captivity for the first time. Even with the initial success at Ash Meadows, wildlife officials continue to collect fish eggs from the original dwellers in Devils Hole cavern. This poses a risk to the shrinking pupfish population, however.
