    Agalychnis callidryas

    The red-eyed tree frog (Agalychnis callidryas) is an arboreal hylid native to Neotropical rainforests in Central America.

    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 stomach is soft and fragile skin, whereas the back is thicker and rougher.

    The red-eyed tree frog has three eyelids, and sticky pads on its toes. Phyllomedusid tree frogs are arboreal animals, 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 stomachs, and shut their red eyes. Thus, they appear almost completely green, and well hidden among the foliage.
