Agalychnis callidryas, known as the red-eyed treefrog, is an arboreal hylid native to Neotropical rainforests where it ranges from Mexico, through Central America, to Colombia. It is sometimes kept in captivity. The scientific name of the red-eyed treefrog, A. callidryas, comes from Greek words kalos(beautiful) and dryas (a tree or wood nymph).
The species has red eyes with vertically narrowed pupils. It has a vibrant green body with yellow and blue with vertically striped sides. Its webbed feet and toes are orange or red. The skin on the red-eyed treefrog’s belly is soft and fragile, whereas the back is thicker and rougher. Red-eyed tree frogs have sticky pads on their toes to cling onto leaves.
