Agalychnis callidryas

Agalychnis callidryas, commonly known as the red-eyed tree frog or red-eyed leaf frog, is a species of tree frog in the subfamily Phyllomedusinae native to forests of Central America to north-western South America. This species, being one of the most recognizable of frogs, is known for its vibrant coloration; it has a vibrant green body with blue and yellow stripes on the side, a white underside, bright red to orange colored feet, and its namesake bright red eyes. Despite its bright coloration, the red-eyed tree frog is not poisonous. Its bright coloration can thus be more attributed to camouflage amongst the greenery of the surrounding jungle, as well as the "startle reflex", which it can use to dissuade predators. During the day, the frog uses its green back to camouflage amongst the leaves, this camouflage being its only defense. If disturbed, the frog flashes its bright red eyes, which may startle predators and allow the frog to escape.

Like all the frogs in its genus, the species is arboreal, possessing long limbs and webbed toes, and is nocturnal, when they mostly hunt for insects. The males of this species are smaller than the females, and they display non-random mating patterns which suggest female choice for specific types of male. They mate and reproduce near ponds, and are therefore found in humid lowlands, especially tropical forests. The embryos of this species are able to respond to incoming predators by hatching early, dropping into the water body to escape.
