Rain Frog, Corcovado National Park, Costa RicaI’m not sure on the exact species here, but I believe this to be a type of rain frog. Photographed on a night hike in Corcovado National Park down on the Osa Peninsula of Costa Rica. Nikon D700 with Nikkor 105mm macro lens, ISO 200, f/16 at 1/60th of a second, two Nikon SB-900 flash units.
