Check out the regenerated tail. These lizards can drop their tails when threatened and scamper away from danger leaving the tail behind to wriggle around and occupy the would-be threat. The tail then grows back, but as you can see here, looks a bit different from the original.
I looked back in my lizard file and saw this alligator my son caught two years ago and kept in a lizard habitat for a couple of days. You can see here how long their tails really are.
Another of the alligators we've seen. I think this is maybe a teenage alligator lizard.
Mostly we see fence lizards like this one I saw yesterday.
