The Atelopus frog is known by many names such as the clown frog or the Costa Rican Variable Harlequin Toad. Whatever you call the frog, it is a neo-tropical toad that was once quite wide spread living throughout Costa Rica and Panama. The species is listed as critically endangered and is thought to be living primarily in Panama today. Photo: Paul Ouboter / Conservation International.
