The Common Frog (Rana temporaria), known also as the European Common Frog or the European Common Brown Frog, is located throughout much of Europe as far north as well north of the Arctic Circle in Scandinavia and as far east as the Urals, except for the majority of Iberia, southern Italy, and the southern Balkans. The farthest west it can be found is Ireland, where it has long been considered erroneously to be an entirely introduced species. These frogs measure about 2.4 to 3.5 inches and...
