Natterjack toads are claimed to be Europe's noisiest amphibian, with the male call audible over several kilometres. Natterjacks are found in southwest and central Europe, but are rare in Britain. They can be found in southwest Ireland, pockets of Norfolk and Lincolnshire, along the coast between Lancashire and Dumfries and areas of Hampshire and Surrey where they've been introduced. Being poor swimmers, they drown in deep water if they can't get ashore. Short limbs mean they can't leap very far, and usually only do so as a startle response before going into their normal running gait.
