 The rediscovered Rio Pescado Stubfoot Toad (<i>Atelopus balios</i>) was number 6 in the 100 Lost Frogs. Uncovered after 15 years in Ecuador by Eduardo Toral-Contreras and Elicio Tapia. Researchers feared that the deadly amphibian chytridmycosis had wiped out this species along with many other closely related species in Ecuador. Photo: © Eduardo Toral-Contreras .
