Marginated tortoises grow up to 40cm in size and are the largest species of Mediterranean tortoise. Males generally grow larger than females and can weigh up to 5kg. Their name comes from the shape of the marginal scutes that flare out and form a skirt shape at the end of their shell. This flaring is more pronounced in males, whereas females are usually broader in shape. This also becomes more prominent as the tortoises grow with age.
