The edible dormouse or fat dormouse (Glis glis) is a large dormouse and the only living species in the genus Glis, found in most of western Europe. Its name comes from the Romans, who ate them as a delicacy.
The edible dormouse is the largest of all dormice, being around 14 to 19 cm (5.5 to 7.5 in) in head-body length, plus a 11- to 13-cm-long tail. It normally weighs from 120 to 150 g (4.2 to 5.3 oz), but may almost double in weight immediately prior to hibernation. It has a generally squirrel-like body, with small ears, short legs, and large feet. Its fur is grey to greyish-brown in colour over most of the body, while the underparts and the inner surface of legs are white to pale buff; the line of demarcation is rather well defined.
Unlike most other dormice, no dark markings are on the face, aside from faint rings around the eyes. The tail is long and bushy, with fur slightly darker than that on the body. Front feet have four digits and their hind feet have five. The soles of their feet are naked. Females have from four to six pairs of teats.
The edible dormouse is capable of limited autotomy; if another animal grasps the tail, the skin breaks easily and slides off the underlying bone, allowing the dormouse to escape. The exposed vertebrae then break off and the wound heals over, forming a fresh brush of hair.
The edible dormouse is found throughout much of mainland western Europe. It is also found on a number of Mediterranean islands, including Sardinia, Corsica, Sicily, and Crete. It is rather more sparsely distributed through central Europe and the Balkans, but can be found as far north-east as the upper Volga River. Close to the Volga River were small groups of the species found at the Zhiguli Mountains, in Russia. They are also found in the Caucasus region, and along the southern coast of the Caspian Sea. Germany has a small population of edible dormice within its borders, ranging from two to six individuals per hectare.
