The Italian stream frog (Rana italica), also called commonly the Italian frog, la rana appenninica, and la rana di terra, is a species of frog in the family Ranidae. The species is endemic to Italy and San Marino.

Description

Adults of R. italica have a head-body length of 7-7.5 cm (2.8-3.0 in). The hind legs are long, but not extremely so. If the hind leg is pressed forward along the body, the "heel" (tibio-tarsal articulation) does not extend beyond the snout. There are pearly granules on the ventral surfaces of the hind legs.[2]

Vocalization

The male R. italica calls only underwater. Calls are usually inaudible to a human listener, unless the calling frog is only slightly below the surface. Three different calls are known: a low repeated "grongron", a modulated "squack", and a short "uh".[3]

Habitat

The natural habitats of R. italica are rivers, intermittent rivers, swamps, freshwater marshes, and intermittent freshwater marshes.

Conservation status

R. italica is threatened by habitat loss.[4]
