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 →

Global Distribution

Where this species is recorded worldwide. Restricted to human observations from 2019 onwards — the same kind of record and the same period the probabilities on this page are built from, so collar-tracking studies, camera-trap arrays and museum specimens are excluded. Around Santa Rosa that removes 5,924 GPS fixes from a handful of tagged jaguars.
