The frog you are most likely to see in Ireland is the common frog (Rana Temporaria), which lives on land in damp habitats for most of the year. It may be found in open woods, hedgerows, fields and gardens, not too far from water. The body colour varies widely, with upper parts usually brown or olive, but sometimes yellowish- orange or grey. The underside is normally paler, and the whole body is blotched or spotted with a darker colour, which helps to camouflage it against its background. This frog has a distinctive dark patch behind its eye. A male common frog is slightly smaller than the female, which measures about 7.5cm (3in.). Frogs move by hopping or leaping, using their long, muscular back legs; they do not crawl. They have very smooth, damp skins. The fully webbed hind feet help them to swim. Frogs eat insects and other invertebrates, such as slugs, snails and worms. On summer days, they like to hide amongst tall plants and come out on warm, damp evenings to hunt. Like all amphibians, it is hard for them to find food during the winter, and they cannot function in cold temperatures, so from about mid-October they hibernate in a sheltered place on land e.g. under a log, or in the muddy bottoms of ponds. Males often hibernate in the bottom of ponds, so that they are already at the breeding site when the females arrive in the early spring. They can take in sufficient oxygen through their skin during hibernation under the water.
