A very variable leaf litter frog, Ceratobatrachus guentheri are born in a multitude of colors. Even siblings can look completely different from each other! The base color can range from tan to yellow, orange, and even lime green in some individuals. Spots can be visible in some individual SILFS, but generally are not present in any significant numbers, if at all.
