On the Origin of a Species: The Common or Viviparous Lizard (Zootoca vivipara)

A short discussion on the common, or viviparous, lizard – true to its name it is quite common but I love them and got some good photos so had to write about them. They are viviparous, so they give birth to live young, which is unusual. They also have different colour morphs which seem to bestow different traits in terms of reproduction.
