Amphibians of Arizona
Being primarily a desert state, Arizona is not overly well endowed with amphibian diversity. Despite this, as well as having a single native salamander, there are a host of specially adapted desert toads, and a number of canyon-dwelling frogs, some of which are threatened with extinction.
Amphibians of Spain
Despite its largely dry climate, Spain has a well-developed amphibian fauna of 9 newts & salamanders, and 19 frogs & toads, with a mixture of typical Mediterranean species in the south, and temperate European species further north.
Reptiles & Amphibians of Derbyshire
Derbyshire is home to four of Britain's six reptile species, although seeing them is often down to good luck. None of the reptiles has a county-wide distribution, although they can be locally common.
