The edible frog (Pelophylax kl. esculentus) is a name for a common European frog, also known as the common water frog or green frog. Pelophylax kl esculentus is the fertile hybrid of the pool frog (Pelophylax lessonae) and the marsh frog (Pelophylax ridibundus).

The marsh frog (Pelophylax ridibundus) is the largest frog native to Europe and belongs to the family of true frogs. It is very similar in appearance to the closely related edible frog and pool frog.

The European tree frog (Hyla arborea formerly Rana arborea) is a small tree frog found in Europe, Asia and part of Africa.
