Common Lizard

The viviparous lizard or common lizard (Zootoca vivipara, formerly Lacerta vivipara) is a Eurasian lizard. It lives farther north than any other reptile species, and most populations are viviparous (giving birth to live young), rather than laying eggs as most other lizards do.
The length of the body is less than 12 centimetres (5 in) (excluding the tail). The tail is 1.25 to 2 times longer than the body, although it is often partially or wholly lost. The limbs are short, and the head is rather round. Males have more slender bodies than females. The neck and the tail are thick. The collar and other scales seem jagged.

The colour and patterning of this species is remarkably variable. The main colour is typically mid-brown, but it can be also grey, olive brown or black. Females may have dark stripes on their flanks and down the middle of the back. Sometimes females also have light-coloured stripes, or dark and light spots along the sides of the back. Most males and some females have dark spots in their undersides. Males have brightly coloured undersides – typically yellow or orange, but more rarely red. Females have paler, whitish underparts. The throat is white, sometimes blue. (Wiki)
