Edible dormouse

The edible dormouse is the largest of all dormice, being around 14 to 19 centimetres (5.5 to 7.5 in) in head-body length, plus a 11 to 13 centimetres (4.3 to 5.1 in) tail. It normally weighs from 120 to 150 grams (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, with a clear line separating off the white to pale buff underparts. Unlike most other dormice, there are no dark markings 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. 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.
