Natterjack Toad

The Natterjack Toad (Epidalea calamita, formerly Bufo calamita) is a toad native to sandy and heathland areas of Europe. Adults are 60–70 mm in length and are distinguished from Common Toads by a yellow line down the middle of the back. They have relatively short legs, and this gives them a distinctive gait, contrasting with the hopping movement of many other toad species.

Natterjacks have a very loud and distinctive mating call, amplified by the single vocal sac found under the chin of the male animal.
