Ranitomeya variabilis is a small poison dart frog species native to the upper Amazon basin in Peru and Ecuador. The species exhibits extreme geographic variation in color pattern, with populations displaying yellow, orange, red, or blue markings against black backgrounds, and has become a model organism for evolutionary biologists studying mimicry and aposematism. Adults typically measure 16-18 mm in length and are found in primary and secondary forest habitats, where they raise tadpoles in phytotelmata (small pools in plants).
