A spectacular eyelash viper and a glass frog are two of the inhabitants discovered by a team of American and Ecuadorian scientists working for Reptile and Amphibian Ecology International in a treasure trove of previously undiscovered biodiversity in a rare and dwindling ecosystem in coastal Ecuador.

Other apparently new species include a blunt-snouted, slug-sucking snake and 30 species of rain frog.
