'Romeo and Juliet' give hope for survival of the Sehuencas water frog

Until recently, Sehuencas water frogs were among the more than 500 species of frogs and other amphibians on the brink of extinction. Just one male, named Romeo, was living in a lab in Bolivia, assumed to be the last of his species. But researchers recently found five more of these frogs in a cloud forest in the mountains of Bolivia. They took one of the females, named her Juliet, and brought her to meet Romeo.
