The Madang big-eyed tree frog (Nyctimystes disruptus) is a type of tree frog that lives in Papua New Guinea. It used to be known as Richard's big-eyed tree frog. Scientists have found this frog in the mountains of central and eastern New Guinea. They believe it might live in other areas too. These frogs are usually found high up, between 1,500 and 2,000 meters (about 4,900 to 6,500 feet) above sea level.

What Does the Madang Big-Eyed Tree Frog Look Like?

Scientists say this frog looks a lot like the Papua big-eyed tree frog. However, the Madang big-eyed tree frog has more webbing on its feet. It also has clearer, short, broken lines on its lower eyelids.

Unique Eyes and Colors

This frog has special eyes. Its pupils, which are the dark centers of the eyes, go up and down. They open from side to side, which is unusual.

The Madang big-eyed tree frog can be many different colors. Scientists have found some that are brown with white spots. Others are gray with purple marks. Some are even green with brown markings on their backs.

How Big Do They Get?

Adult male frogs are usually about 7.4 centimeters (2.9 inches) long. Female frogs are a bit larger, growing to about 8.0 centimeters (3.1 inches) long.

Understanding Its Name

For a while, scientists thought another group of frogs, called Nyctimystes oktediensis, was a completely different species. But later studies showed that these frogs are actually the same as the Madang big-eyed tree frog.

In the local Kaironk language, people have two names for this frog: kwyos and gepgep.
