The mimic poison frog (Ranitomeya imitator) is a favorite for its wide variation in color patterns. Four distinct morphs are known for the species, each a blend of vibrant hues. The morphs are thought to have evolved through a phenomenon called mimetic radiation, in which a species comes to closely resemble different model species. In the case of the mimic poison frog, those models are other species of poison frogs, like the splash-back poison frog (R. variabilis) and the red-headed poison frog (R. fantastica), that inhabit different geographical areas of central Peru—areas that all lie within the range of the mimic poison frog. At the edges of those areas, contact between different morphs of the mimic poison frog results in the generation of hybrids with truly unique color patterns. Some of those patterns may provide a reproductive advantage, suggesting that the mimic poison frog is evolving right in front of our eyes.
