The fox is a highly adaptable species. It is found in almost all habitats from salt marshes and sand dunes to the tops of mountains. In Britain, more than elsewhere in Europe, foxes have also adapted to life in urban surroundings.
'Fantastic Mr Fox', the story by Roald Dahl, was made into an animated film in 2009 with the voice of George Clooney as Mr Fox.
