About the Pyrenean frog

The Pyrenean frog or Pyrenees frog (Rana pyrenaica) is a species of frogs in the family Ranidae found in the Pyrenees mountains of France and Spain. Its natural habitats are fast-moving mountain streams and their surroundings. The IUCN lists it as "endangered".

The Pyrenean frog is the smallest species of brown frog in Europe, with adults reaching a snout-to-vent length of about 33 to 45 mm (1.3 to 1.8 in), females being slightly larger than males. The snout is blunt and rounded and the nostrils are more widely separated than are the eye bulges. The tympani are small and not always visible and the dorso-lateral folds are fairly close together. The hind feet are completely webbed apart from the tip of the fourth toe. This frog is creamy-brown, buff, greyish-brown, reddish-brown or olive-grey with rather indistinct blotches of greenish-brown or brown. The hind legs are faintly barred. The upper lip is often noticeably pale and the throat and underparts are whitish with the belly sometimes flushed with yellow or pink, especially under the thighs. It differs from the common frog (Rana temporaria) by being smaller, having a less-pointed snout and less-distinct markings... Wikipedia →
