Lost & found: Rare species rediscovered
Thousands of species of amphibians are endangered and hundreds have already disappeared, but in recent years, a team of scientists and conservationists have re-discovered some of these "lost" species and uncovered previously unknown varieties.
A new book "In Search of Lost Frogs," by conservationist and photographer Robin Moore, showcases the results of expeditions to find the world's rarest amphibians, including some that were thought to be lost forever.
This image shows a juvenile Macaya Breast-spot Frog, a critically endangered species in the Massif de la Hotte mountain range of Haiti.
One of the smallest frogs in the world, it was rediscovered in 2010 after nearly 20 years.
