The natterjack toad (Epidalea calamita) is a toad native to sandy and heathland areas of Europe. Adults are 60–70 mm (2.4–2.8 in) in length, and are distinguished from common toads by a yellow line down the middle of the back and parallel paratoid glands. They have relatively short legs, which 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. Wikipedia →
