Going green

Dear Val and Malcolm,

It is that time of year when the animal kingdom is pairing up but no rude pictures here though.  I photographed these green lizards - Lacerta viridis, topping up on their tan but this prompted a question, do reptiles get sunburnt?

                          Apparently the scales of reptiles protect the inner dermis, and they also retain moisture, which stops the reptiles from dehydrating.   I did some additional research and found a study which demonstrated that there is a variation between species, in terms of the transmission of UV light through their skin.  This variation also found that this difference, affected the basking habits of reptiles, those with a higher tolerance would stay in the sun longer.
