The marginated tortoise is the largest European tortoise, reaching a weight of up to 5 kg (11 pounds) and a length of 35 cm (14 inches). Its shell is oblong and has a notable thickness around the middle of the body. The posterior end of the shell has a saw-like formation, flanged outward like a bell. The carapace of adult specimens is almost completely black, with yellow highlights. The ventral shell is lighter coloured and has pairs of triangular markings with the points facing the rear of the animal. The front sides of the limbs are covered with large scales. In old female specimens, the rear flaps of the underside of the plastron are somewhat moveable. The tail is notable for a lengthwise marking and for an undivided carapace over the tail. Males have a longer tail, which is thicker at the base than the females. Their underside is more strongly indented. Males are also often larger than the females. The females lay their hard-shelled spherical eggs in the soil in May and June.
