I took this photo in September 2011, when I was backpacking Costa Rica with a friend. We found it on a night-tour of a small nature reserve owned by a local man. We saw a lot of wildlife on the tour, but this one was my favourite, probably because of the way it just sat there posing for the camera. They generally seemed to be quite docile and I was able to hold one without it trying to escape. I think the lighting is good as well, giving it a shiny, waxy-looking body. You can see how the frog is designed for tree-climbing rather than swimming, with the feet which are not webbed. It also has huge eyes, which help with nocturnal living.
