Red-eyed tree frog, Costa Rica - a photo on Flickriver

            The red-eyed tree frog (Agalychnis callidryas) is an arboreal frog native to Neotropical rainforests where it ranges from Mexico, through Central America, to Colombia. The specific name of the red-eyed tree frog, Agalychnis callidryas, comes from Greek words kallos (beautiful) and dryas (a tree or wood nymph).
As its name suggests, the red-eyed tree frog has red eyes with vertically narrowed pupils. It has a vibrant green body with yellow and blue, vertically striped sides. Its webbed feet and toes are orange or red. The skin on the red-eyed tree frog's belly is soft and fragile, whereas the back is thicker and rougher. Red-eyed tree frogs have sticky pads on their toes.  Tree frogs are arboreal, meaning they spend a majority of their lives in trees; they are excellent jumpers. Red-eyed tree frogs are not poisonous and rely on camouflage to protect themselves. During the day, they remain motionless, cover their blue sides with their back legs, tuck their bright feet under their bellies, and shut their red eyes. Thus, they appear almost completely green, and well hidden among the foliage. The large red eyes not only allow identification, but also serve as a defensive adaptation. When a red-eyed tree frog detects an approaching predator, it abruptly opens its eyes and stares at the predator. The sudden appearance of the red eyes may startle the predator, giving the frog a chance to flee.
