Iberian frog
The Iberian frog or ''rana patilarga'', (''Rana iberica''), is a species of frog in the family Ranidae found in Portugal and Spain. Its natural habitats are rivers, mountain streams and swamps. It is threatened by habitat loss, introduced species, climate change, water contamination, and increased ultraviolet radiation.〔Ayllón E., Domínguez C., 2001: “Situación actual y problemas de conservación de la rana patilarga en la Comunidad Autónoma de Madrid. Boletín de la Sociedad para la Conservación de los Vertebrados, 8–9: 7–15.〕
==Description==
The Iberian frog can grow to about in length but a more normal size is . Females tend to be larger than males. The tympanum can be seen just behind the eye and is about half its size in diameter. From the side of the head to the groin is a distinct ridge, the dorsolateral fold, which distinguishes this species from the common frog (''Rana temporaria''). The skin is smooth with fine granulations. The colour is very variable, being mainly olive, reddish or greyish-brown, sometimes with darker markings. A dark streak runs between the nostril and the eye, and a thin, white line marks the upper lip. The hind legs are sometimes barred with dark brown. The hind feet are more completely webbed than the common frog. The underside is pale, sometimes with darker spots, but the centre of the throat is not spotted.〔(''Rana iberica'' ) AmphibiaWeb.
