Family-Animalia: Gliridae

A dormouse is a rodent of the family Gliridae (this family is also variously called Myoxidae or Muscardinidae by different taxonomists). Dormice are nocturnal animals found in Africa, Asia, and Europe, and are particularly known for their long periods of hibernation.

As only one species of dormouse – the hazel dormouse – is native to the British Isles, in everyday English usage "dormouse" can refer either to that one species or to the family as a whole.

The English name of the species derived from the French dormeuse, and the latter in turn possibly from the Languedocien radourmeire.
