The red-eyed tree frog is one of Costa Rica’s most iconic amphibians, known for its striking appearance. This small, vibrant green frog has large, bulging red eyes, blue sides, and orange webbed feet, creating a vivid contrast that serves as a defense mechanism known as 'startle coloration.' Native to the rainforests of Central America, the red-eyed tree frog is primarily nocturnal, spending its days hidden among leaves and becoming active at night to hunt insects—exactly when I hoped to capture it on camera.
