Robot Frog Attracting Potential Mate (VIDEO) University of Texas at Austin This video is under embargo. Please login to access this video. To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video Caption When choosing a potential mate, female túngara frogs listen to the sounds of the male calls, which are based on a pattern of "whines" and "chucks." If visible, the sight of the male frogs inflating their vocal sacs adds to the appeal of the calls. In this video a female tungara frog approaches a robofrog inflating its vocal sac. The female can also hear recorded mating calls playing.
