Tree frogs are small amphibians known for their ability to climb and live in trees. They have long, sticky toes that help them grip branches and leaves. Most species are found in tropical and subtropical regions, where they thrive in humid environments. Their vibrant colors often serve as camouflage or warning signals to predators. These frogs are primarily nocturnal, meaning they are most active at night. They communicate using a variety of calls, which can vary significantly between species. Tree frogs play an important role in their ecosystems, helping to control insect populations and serving as prey for larger animals.
