Signaling behavior in the Red-eyed tree frog
Red-eyed tree frogs, Agalychnis callidryas (Hylidae), form nocturnal mating aggregations in vegetation over Mesoamerican wet forest ponds. 
Males defend calling sites, maintaining a spacing of at least 0.5 m. Most females pair with one male, but multimale amplexus and paternity occur, and aggression between amplectant and unpaired males is common. 
During contests over females, competing males use chuckle calls and perform a display wherein the signaler raises his body off the plant and then rapidly contracts and extends his hindlimbs, shaking his hind end (tremulation). 
Because tremulating males likely excite strong, stereotyped vibrations in plants, it has been hypothesized that this display generates a vibrational signal, or possibly a bimodal signal with both visual and vibrational components.

Wonder Woman Comic1941, Smithsonian Libraries“Not even girls want to be girls so long as our feminine archetype lacks force, strength and power,” psychologist William Moulton Marston wrote in 1943. He had already modeled a new archetype on his wife and fellow psychologist, Elizabeth Holloway Marston, and Olive Byrne, a homemaker who lived with the Marstons in a relationship that included shared children. Wonder Woman, a magic-lasso-toting dispenser of justice, broke the superhero glass ceiling in All Star Comics in December 1941.
