The frog otherwise known as "Rana temporaria" or the common frog is Ireland's most habitual amphibian. Frogs like to stay in damp areas such as ponds, drains, hedgerows and ditches. During the winter frogs can be found living under tree stumps or rock piles. So there are plenty of desirable homes for the common frog in Dún a Rí forest park.

Male frogs are usually smaller than female frogs in size. Female frogs can lay thousands of eggs throughout their life. Their eggs take form in a large cluster known as "egg masses" or "frogspawn" and after around 35 days, tadpoles begin to emerge. Out of thousands of tadpoles, few will make it to adulthood. The common frog has a lifecycle of approximately seven - eight years.

Frogs consume oxygen through their skin and lungs and some have the ability to change their colour to suit their current environment. Their eyes and nostrils are on top of their heads so they can see and breathe when in water. The common frog has webbed feet and long sticky tongues which they use to catch insects such as snails, flies, slugs, worms and spiders. During the breeding season common frogs don’t eat at all!

"Batrachomyomachia" or "The Battle of Frogs and Mice" is a mock epic or parody of the Iliad, attributed to Homer by the Romans. This story sees the mice declare war with the frogs because the "Frog King" swims across a lake, with the mouse on his back on the way to visiting King Frog’s home. However, they meet a water-snake. The Frog dives, forgetting about the Mouse, who drowns.
