Performed a quick google search using the info above the picture, and it looks like it's a real species, but the photo is VERY altered.

These were a couple of pictures that came up when "Atelopus varius" was typed in. Chances are that whoever made this picture simply changed the color of where the yellow is into that pinkish hue. Either that or found a real picture and made the colors much stronger/vibrant than they really are.
