Red-eyed tree frogs (Agalychnis callidryas) are renowned for their vibrant green bodies and large red eyes, which serve as a defense mechanism to startle predators. These frogs are native to the tropical rainforests of Central America, including regions of Mexico, Costa Rica, Nicaragua, and Panama. They are arboreal and spend most of their lives in the trees, using their sticky toe pads to grip branches and leaves. Interestingly, their bright colors aren't just for show; they also serve as camouflage during the day when they rest on green leaves, blending seamlessly with their surroundings.

These frogs are nocturnal and become active at night to hunt for insects, which make up the majority of their diet. One of their remarkable adaptations is their ability to jump long distances to evade predators and to catch prey. During the breeding season, males attract females using their distinctive calls, which are loud and can be heard from quite a distance. Females lay clutches of eggs on leaves above water bodies, and once hatched, the tadpoles drop into the water where they develop into frogs over several weeks. Red-eyed tree frogs are popular in the pet trade due to their striking appearance and relatively easy care in captivity, although their conservation status in the wild is threatened by habitat loss.
