Jiménez de la Espada, 1872
Madre Selva field station, Depto Loreto, Peru. January 11, 2011
A frog (Craugastoridae) that looks a lot like a toad, Oreobates quixensis is covered with warts and tubercules, including its fingers and toes. They are quite common on forest trails, ant hills, treefalls, anywhere the earth is exposed and laid bare, and they blend in quite well.
