Little Fish

I spent the holiday weekend on Whidbey island. It was quite nice.

We went out for a walk at Double-bluff Beach. There were quite a few things of interest there, including moon snail egg collars (looked like a funnel made of sand), various crab, a heron fishing in the low tide, and these little fish. We found several of these fish in the sand a fair distance from the sound (several meters), though there were small amounts of water nearer on the beach. This one at least was alive and got a free ride back to the sound courtesy of the nine year old who is attached to the foot.

I'm not really sure what would be a good resource for identifying fish like this.
