Italian cave salamander


The Italian cave salamander is a species of salamander in the family Plethodontidae. Endemic to Italy, its natural habitats are temperate forests, rocky areas, caves, and subterranean habitats. It is threatened by habitat loss.

Description

The Italian cave salamander is a slender species with short limbs and grows to a length of about including a short tail. The head is broad with prominent eyes and there is a distinct groove between the nostrils and the edge of the lips. The feet are partially webbed. It is dark in colour with mottled reddish or yellowish markings and a dark belly. In the north of its range it is more variable in colour and sometimes hybridises with Ambrosi's cave salamander.

Distribution and habitat

The Italian cave salamander is native to northern Italy where it is found in the northern and central Apennine Mountains. Its range extends from the Province of Lucca and Province of Reggio Emilia southwards to the Province of Pescara. It is found in wooded valleys, on rocky outcrops and in caves and underground waters, often in limestone areas, at altitudes of up to above sea level.

Behaviour

The Italian cave salamander is usually found in areas of limestone rock, but sometimes in sandstone or ophiolitic areas. It is agile, climbing on cave walls and rocky outcrops. The female lays a small clutch of eggs in a crevice and these hatch by direct development into miniature salamanders.

Status

The International Union for the Conservation of Nature has assessed the Italian cave salamander as being "near threatened". This is on the basis that, although it is common over much of its range, its total extent of occurrence is less than and suitable habitat may be declining locally.
