Also known as Japanese Treefrog, Far Eastern Tree Frog
Adorned in vibrant green skin that can shift to brown or gray to match nearby vegetation, Japanese tree frogs are famed for their remarkable cold tolerance, surviving extreme sub-zero winter temperatures in a state of supercooled dormancy. During spring breeding choruses, males inflate prominent vocal sacs to serenade females around flooded rice paddies and wetlands. Beyond their ecological versatility on Earth, these adaptable amphibians even gained international fame as microgravity research subjects aboard space stations.
