Oh, I'm a lucky mom.
The boys came home from Grandpa and Grandma's with more lizards. Now they each have their own. That is, if they'll coexist in the aquarium.
You can see two in this photo. Although one is in motion and blurry, you can see the color variation.
Then, while they were turning over the pavers to look for food for the lizards (bugs, centipedes, snails), they found an as-yet-un-photographed salamander. He looks a bit like this, and is probably an Ambystoma macrodactylum - a long-toed western salamander.
