These frogs have been observed waving their arms around in what certainly looks like some sort of signal, greeting, or similar form of communication. According to the observation, it appeared as these frogs were waving to each other. These signals may simply be a muscle stretching exercise lol, or it may be some form of communication behavior or signal. However, it clearly resembles the hello/goodbye waving of people, and this makes it all the more mysterious.
This is also mating behavior in atelopus species. Here's a video of a. zeteki..
