This one did not seem to be full size, although I am not sure what size they reach when mature.
No interactions present.
Hi Robert it is full size female, the males get a bit bigger
The males have bigger heads, but generally females can grow longer and heavier in the body. This one looks like a full size adult to me
I figured that it might be female as it seemed well developed and there is usually a large male in the same few square metres.
Thanks MM, always interesting. I saw a 'Sand Lizard' breeding centre at Avon Heath Country Park last week and chatted with the manager; also very interesting and successful.
