Unlike subatomic particles, snakes are pretty easy to observe, especially when they shed their skin and leave it behind. The other day I found a snake skin next to the burrow of Stump Gopher in my front yard.
I figured it was some ordinary no-big-deal snake that shed it, but what if it was an indigo snake? That's a big-deal endangered snake that often hangs out in gopher holes. If that was an indigo snake skin that would be cool. I was in the middle of something at the time so I got a plastic storage container out of the house and got the head part of the skin and saved it for later. Eat your heart out, Heisenberg.
When I got around to it I Googled Black Racer Head Scales. The image results gave me a nice line drawing (courtesy of the Florida Museum of Natural History). I compared that to my shed scales.
