Smoky jungle frog (Leptodactylus savagei). This species of frog is northern South America as well as parts of Central America. Adults can grow up to 18 centimetres in length. They have brownish-coloured backs with black markings and cream-colored underparts. When threatened, smoky jungle frogs will try to appear larger by inflating their lungs and standing tall on all four legs. Photographed in the Amazon jungle in Loreto, Peru.
