The Red-eyed Tree Frog (Agalychnis callidryas)
The abundance of moisture in a rainforest allows many different kinds of amphibians, such as this Red-eyed Tree Frog, to live there. Amphibians lose moisture through their skin and need a moist environment. The Red-eyed Tree Frog lives in the canopy of the rainforest most of the time, but comes down to ponds when it needs to breed. These frogs are quite common in the rainforests of Panama, Costa Rica, and Nicaragua.

Tropical Tree Frog (Hyla ebraccata)

This tiny treefrog (less than 1" or 2.5 cm long) lives high in the rainforest canopy for most of the year. During the rainy season, it descends to swamps and ponds in the rainforest for breeding.

Because they are so small, they are at great risk of predation when breeding. The bold little males sing from exposed perches hoping to lure a female in, but trying at the same time to avoid getting eaten. Cat-eyed Snakes and Frog-eating Spiders are among the most common threats, but Bulldog Fishing Bats and other winged predators also threaten the frogs.

If successful in breeding, the female lays eggs on a leaf that eventually fall into the water. There they hatch into beautiful gold and black striped tadpoles, where they quickly grow and metamorphose into frogs. The young frogs then head for the trees until the next breeding season.
