Western Side-blotched Lizard

This lizard was enjoying the morning sun. Its tail is growing back so it's shorter than usual. "A small brownish gray lizard with small smooth granular scales on the back, larger scales on the head and limbs, a gular fold, a long thin tail and a dark blue-black mark on the sides of the chest behind the front limbs, which gives this lizard its name.. This mark is sometimes faint or absent. "
