Common frogs are found in the continent of Europe, from Great Britain to central Russia. Common frog (Rana temporaria) is also known as grass common green frog or russet frog. It is a semi-aquatic amphibian which means they can survive on land and water but prefer to stay in moist regions around a source of water. The common frog has three distinct life stages, from aquatic larva, followed by terrestrial juvenile, and then adulthood. Common frogs are not same as Bufo Bufo, the common toad, but they are a different common frog species altogether. The common frogs are born with different colors from olive green to grey-brown, brown, olive-brown, grey, yellow, pink, red, and rufous. They can lighten or darken their skins to match their surroundings. They also have dark patches on the back, stripes on the hind legs, and a dark mask behind their eyes. The common frog has brown eyes with horizontal pupils and transparent inner eyelids to protect its eyes while swimming.

Male and female common frogs can be differentiated by their size; the females are larger than the males. The common frogs can breathe through their lungs and their skin. Loss of habitat is one of the major causes for concern for the decline in the common frog population. The Amphibian and Reptile Conservation Trust (ARC) is working on conservation of amphibians and reptiles including these species. Read on for some of the most interesting common European frog facts.
