Please ignore my ID!

I think I must have taken too much sun today as my eyes seem to have picked out details that weren't there!

Common lizard

No worries Vinny we all have off days, I mis-sexed a couple of adders on iSpot yesterday!

Vinny is correct

This lizard was identified early on by Vinny as a common wall lizard but has been identified since and agreed by a number of people as a viviparous lizard. It is one of the few amphibian and reptile observations on iSpot I hadn't agreed or added an identification too, as it just didn't seem right but I was hesitant to disagree with so many.

I've now thoroughly gone through it and I believe Vinny was right, it's a common wall lizard. I have determined this by counting the dorsal scales (which I make approximately 54, by counting from the centre of the back to the belly and doubling the number). Arnold and Ovenden's guide gives the dorsal scale count range for viviparous lizards as 25-37 and common wall lizards as 42-75. I've also had a scale count on some of my photos of both species to check this and they fall within these ranges. Whilst the odd individual may fall outside this range I don't think a viviparous lizard would have a scale count this far out (or my counting be that inaccurate). Viviparous lizard dorsal scales are also usually slightly keeled, which these don't appear to be.

In terms of body shape, it does look more like a wall lizard with more flattening than you would see in a viviparous lizard.

I agree, wall lizard.

The patterning, flat body and general appearance highlight that is indeed a wall lizard.

Thanks Mark. It's an

Thanks Mark. It's an interesting observation as I don't believe there have been wall lizards recorded here before.
