Named the Phu Luang Cliff frog after the national park where it lives, the amphibian, which can grow to 3.5 inches (8.9 centimeters) has a naturally green body that can turn brown.

Scientists have found the rare frog in mountain waterfalls and creeks between 3,280 to 4,291 feet (1,000 to 1,500 meters) above sea level, Tanya Chan-ard, curator of Bangkok's National Science Museum, told the Associated Press.

The frog was discovered a few years ago, although scientists have only recently began studying it, Tanya said.
