Red-eyed Tree Frog (Agalychnis callidryas)

The Red-eyed Tree Frog is easily one of the best recognized frogs in Costa Rica. It is featured in most ads promoting eco-tourism activities to both nationals and foreigners. Its colors are very bright and varied, ranging from the white belly and throat, green dorsum and sides of the arms and legs, blue on the inside part of the arms and legs, the orange hands and feet, and the reddish eyes with conspicuously vertical black pupils. Like many other tree frogs, they are nocturnal and arboreal.

The eyes of the Red-eyed Tree Frog are fascinating and pop with color even on the dark. The underside of the frog is white, which contrasts with the dark forest they tend to inhabit

The iris is all covered in veins and the eye is large in comparison with the body, helping this species see very well in the dark forest
