The Costa Rican Variable Harlequin Toad (Atelopus varius), also known as the clown frog, is a neo-tropical true toad from the family Bufonidae.
The Harlequin toad is a diurnal frog often found on rocks or in crevices along streams in humid lowland and montane forests. It is primarily a terrestrial species, only entering the water during breeding season, relying on spray from streams for moisture.
