One young lizard hunting among the vegetation in the dunes:
And a dramatic view of what I think is probably a male grasping a female with his mouth (see below). After seeing this, I did a little research and read that males will do this prior to mating.
I think these are Northern Alligator Lizards (Elgaria coerulea), but I didn't get a close view of them, so I'm hesitant to say for sure. [Interesting note: Northern Alligator Lizards will give birth to live young during the summer and early fall.]
