The underparts, including the inner sides of the limbs, the fingers and toes, is greyish-blue to black-blue with striking, bright yellow to orange spots or patches, usually covering more than half of the underside.

It breeds in ponds, wetlands, ditches, ruts, pools, and drinking troughs.

[1] 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.

If attacked by a predator, it arches its back to expose its brilliantly coloured aposematic underparts which give warning of its toxicity.
