The dormouse is a rodent of the family Gliridae (this family is also variously called Myoxidae or Muscardinidae by different taxonomists). Dormice are mostly found in Europe, although some live in Africa and Asia. They are particularly known for their long periods of hibernation. As only one species of dormouse is native to the British Isles, in everyday English usage "dormouse" can refer either to that one species (the hazel dormouse) or to the family as a whole.
