The Common Lizard is a small, very active lizard, and can often been seen basking on stone south facing walls, or flat surfaces. They can be found in a range of colours, grey, ginger or a dull green being the most commonly encountered variants. Adult Common Lizards will grow to a length of 130 - 150 mm (including tail).
Female Common Lizards are noticeably fatter than males, especially when gravid. A male head is broader than a female, and they will have an orange underside, whereas the female is a more yellow underside. The tail of both sexes is long and will have a rough appearance, however, many sightings of lizards will be with either no tail, or a tail that has regrown shorter and stumpier than the original. Common Lizard's drop their tails if threatened, and this includes being picked up incorrectly by their tails.
