?❤️?The Pirre harlequin frog is one of a number of imperiled frog species @amphibianrescue hopes to return to the wild after scientists find a way to cure or manage chytrid. Help us #FightForFrogs by supporting @amphibianrescue today. Follow the link in our profile to donate and @goldenfrogsoftware will match every $$. Panamanian golden frogs and others in the Atelopus family, like the Pirre harlequin frog in the video here, call to one another when they’re breeding, but without eardrums, the sound is hard to hear over the rush of the river around them. So they wave, using this form of sign language or “semaphore” to communicate not only to attract potential mates, but to defend their territory and maybe even to greet one another.
