 that has the ability to glide. That is, it can descend at an angle of less than 45° relative to the horizontal. Arboreal frogs (non-flying frogs) can also descend vertically, but only at angles greater than 45°, which is referred to as parachuting. Flying frogs have evolved independently among 3,400 species of frogs from both New World

).
They have suction pads on their webbed feet which helps their balance in the high trees that they live in.

Habitat

The environment and temperatures of these areas that they live in are not extreme. They have to have slow moving temperatures or they will not be able to survive. There is normally a very moist rain forest or tropical land. They survive by being the same color as their surroundings. They spend most of their time hanging on trees and eating at night.

Species

There are many different species of flying frogs; here is a small portion of the very interesting types of these amazing animals:Annam flying frog, Rhacophorus Annamensis, inhabit in the annamese jungles in Southeast Asia.
Chinese Gliding Tree Frog, Polypedates Dennysi, inhabit in China.
Javan Gliding Frog, Rhacophorus Reinwardtii, inhabits Indonesia, parts of China, Malaysia, Vietnam, and Laos.Wallace frog, Racophorus nigropalmatus, inhabits the jungles of Malay Peninsula, and Indonesia. They spend their life entirely in trees only coming down to mate and lay their eggs in small ponds or waterways.

Diet

Flying frogs are carnivorous; their diet consists of insects that inhabit the jungle. These jungles include: the jungles of Malaysia, Borneo and many others.

)

This frog usually grows to be about 4 inches or about 10 centimeters. Wallaces flying frog can be distinguished from other frogs because they have black marks between the webbing in their feet. These frogs are usually a bright green color with yellow sides.

Chinese gliding tree frog (Polypedates dennysi)

This males of this species can grow to be 3.5 inches (8.9 cm), the females can grow to be 4 inches (10.2 cm). They have large black eyes. This frog is also a bright green color. On their sides they have black and white markings on their sides, but on frogs younger than one year these are just white lines.

)

Like in the Chinese flying frog the females of this species are a little bigger around 4 inches (10.2 cm). This frog is usually a light gray color but you can also find them to be brown or a dark red color, and in some cases bright yellow.

Javan gliding frog or (Rhacophorus reinwardtii)

Also like the other two frogs the females grow to be a bit larger but they only grow to be 3.5 inches (8.9 cm). They can be either light green or dark green colors and they have black spots around the back and the head. Males can have more colors on the sides of the abdomen like orange,green,purple,black and yellow. Their eyes can be light green,light yellow or light grey. They have horizontal pupils.
