Description

The Italian pool frog grows to a snout-to-vent length of about 8 cm (3.1 in) and has a pointed snout and triangular-shaped head. The tongue is notched and it has vomerine teeth in the roof of its mouth. The skin is smooth and not warty. The colour is variable and depends on the animal's location, but is usually some shade of green with black spots, but may be reddish-brown or grey. There is a pale stripe running along the centre of the back. The underparts are greyish-white marked with dark blotches and the hind legs have dark stripes. Males have a pair of external vocal sacs on either side of the mouth which are only visible when the animal is calling. The voice is a series of guttural croaks each lasting up to one and a half seconds.[2]

Distribution and habitat

The Italian pool frog is native to the mainland of Italy, south of Rimini and Genoa, and to the islands of Sicily, Elba and Corsica. It has been introduced into Sardinia. Its typical habitat is sluggish streams and rivers, lakes and swamps and their environs, and it is present at altitudes of 1,800 metres (5,900 ft) or more. It has been introduced into the United Kingdom but whether it persists there is unclear.[1]

Status

The main threat to the Italian pool frog is the draining of its aquatic habitats; as a result of this, the population appears to be declining at a slow rate. However, the frog has a wide range, is common in many places and has a large total population, so the International Union for Conservation of Nature has assessed it as being of "least concern".[1]
