The Scientific name is now: Zootoca vivipara this was formerly: Lacerta vivipara
This species is able to live in very cold climates due to the female's ability to incubate and hatch eggs inside her body, allowing her to give birth to live young. The male is usually much larger than the female (pictured), and sometimes they can grow to more than 20cm long. About half of the lizard's length is its tail. If threatened or an attempt is made to grab a lizard, they will frequently drop their tails, leaving only a slightly bloody stub. The dropped tail continues to thrash around so as to keep a predator's attention while the owner makes a hasty escape. Eventually the tail grows back. Sometimes it can grow a forked second tail. Even more spectacular is the fact that if a rare accident occurs and a leg gets cut off, it is able to regrow a new leg or even regenerate a new eye. If you look at the images you will notice that some smaller ones have a blue tails, these are the juveniles. When we shoot these images, it was the first time we saw these blue tails and thought it were different species.
