This is a list of European amphibians. It includes all amphibians currently found in Europe. It does not include species found only in captivity or extinct in Europe, except where there is some doubt about this, nor does it currently include species introduced in recent decades. Each species is listed, with its binomial name and notes on its distribution where this is limited.
Conservation status - IUCN Red List of Threatened Species:
A tree frog is any 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, even though they are not closely related to each other.
Many millions of years of convergent evolution have resulted in almost identical morphology and ecologies. In fact, 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.
