About Pelophylax saharicus (Boulenger, 1913)
The Sahara frog (Pelophylax saharicus) is a large frog species. An exceptional female specimen collected from Morocco measured 104.5 mm (4.1 in) from snout to vent. This species is sometimes confused with Perez's frog (Pelophylax perezi), and some published descriptions of the Sahara frog may actually partially describe Perez's frog instead. Its head is as wide as it is long, with an oval snout and horizontal pupils. Males have a pair of vocal sacs on their throat. A distinct ridge runs from the nostrils, across the upper eyelids, and continues to the groin, separating the frog's back from its flanks. The hind feet are webbed. The Sahara frog's body coloration is variable; individuals can be green, brown, or a mix of the two, and sometimes have darker spots. Some individuals have a yellowish or greenish stripe running along their spine. The legs are always marked with spots or bars. The Sahara frog is native to North Africa, and its natural range includes Western Sahara, Morocco, Algeria, Tunisia, Libya and Egypt. It is an aquatic species, found in and near streams, oasis pools, irrigation canals, lakes, and other bodies of water.
