You might have learned about mimicry in high school biology class. If so, perhaps you encountered the viceroy butterfly, whose wing pattern matches the monarch's. Or maybe you came across the scarlet king snake, whose vivid coloring resembles the Eastern coral snake's. These are the classic examples of the phenomenon, which helps organisms to avoid predation. More recently, scientists have identified chemical, acoustic and even behavioral forms of mimicry, as this article in the May issue of Scientific American explains.

Meet some of these new mimics in this slide show.
