Distribution and habitat

The Apennine yellow-bellied toad is endemic to Italy, where it is found south of the Valley of the River Po, throughout the Apennine Hills and southwards to the tip of the Italian mainland. Its range varies from above sea level. It is found in ponds and ditches in forests and open areas. It breeds in ponds, wetlands, ditches, ruts, pools, and drinking troughs.

Behaviour

The Apennine yellow-bellied toad is a diurnal species, and hibernates from about November to April. Breeding activity starts soon after the toads leave hibernation, and females lay multiple clutches of a few eggs in temporary water bodies. This species produces a toxic secretion from its skin. If attacked by a predator, it arches its back to expose its brilliantly coloured

Status

This toad seems to be declining in numbers, although it is not clear why. Changes in agricultural practices may partly be to blame or the fungal disease chytridiomycosis may be the cause. The
