Post-edit, USM. Photo taken at Lowry Park Zoo in Tampa, Florida. This tiny frog was perhaps the size of your thumbnail. He was in a 20 gallon glass aquarium with a handful of other colorful poison dart frogs. I used a flash, but angled the camera to avoid glare. Poison dart frogs do not need camoflauge because as their name suggests they are highly poisonous. Their bright coloration alone stands as a warning. They can even be fatal to humans.
