Yep very nice
Great photos. The other day someone asked me what it is about slow-worms that makes them lizards rather than snakes, and I didn't know the answer. Is it something to do with the internal structure/skeleton?

I think it is because they have eyelids like other lizards. Why they are not 'snakes with eyelids' rather than 'legless lizards' is another question entirely.
Hi These are really great shots.
You are right, the most obvious difference that makes the slow-worm a lizard rather than a snake is the presence of an eyelid - snakes never have them.
Slow-worms shed their skin in patches rather than in one piece as in snakes.
They can also shed their tail when threatened, a lizard trait.
Unlike snakes they have external ears though these are usually very difficult to see.
The tongue is short and notched rather than long and forked.
Most snakes have rough, overlapping scales; slow-worms and other lizards have smooth, non-overlapping scales.
The head, like skinks, is the same width and shape as the body, snakes always have a distinct head.
Finally, they have vestigel limbs, pelvis and shoulders.
I hope this helps

Thanks Graham and Vikram, I am now well-prepared for the next time someone asks the question!
Thanks for the praise of the photos, I only wish I'd figured out how to properly use the macro mode on the camera before I took these :-)
