Tree frog
（重定向自Treefrog）
A tree frog is any species of frog that spends a major portion of its lifespan in trees, known as an arboreal state. Several lineages of frogs among the Neobatrachia have given rise to tree frogs, although they are not closely related to each other.
Many millions of years of convergent evolution have resulted in almost identical morphology and ecologies. They are so similar as regards their ecological niche that in one biome where one group of tree frogs occurs, the other is almost always absent. The last common ancestor of some such tree frog groups lived long before the extinction of the dinosaurs.
