Red-eyed Tree Frog

Agalychnis callidryas

Animals of South America Back
Red-eyed tree frogs are most well known for their huge, bright red eyes. They are a highly recognizable image that is often used to symbolize the cause of saving the world's rain forests.

Some believe that the bright, red eyes act as a defense mechanism called “startle coloration”. If a predator were to stumble across a red-eyed tree frog, the frog would awaken, its eyes would pop open widely and the sudden brightness of their red eyes might startle a predator enough to give the agile frog a chance to jump away to safety.

Its green coloring helps it to stay hidden among the leaves of trees, waiting for insects or other small animals to come their way. Red-eyed tree frogs are arboreal and are excellent climbers. They have suction-cup toes that help them attach to the underside of leaves, where they rest during the day. This frog is nocturnal and is active at night.

While most frog species lay their eggs directly into the water, the red-eyed tree frogs lay their eggs on the underside of leaves that hang over water. When the eggs have developed into tadpoles, the tadpoles swim around within their eggs until the egg ruptures. All the eggs in the clutch hatch within a minute of each other and the combined fluids from all the ruptured eggs help to wash all the tadpoles down the leaf and into the water below.


Insects, including crickets, moths, flies, grasshoppers; sometimes smaller frogs, that they catch with their long sticky tongues.
