I had a colonoscopy yesterday. The day before the procedure, I walked out to the car and almost stepped on the longest banana slug I’d seen. And I’ve seen a lot.
This slug was so attenuated I almost mistook it for a branch from my apple tree. I watched it for a while and noticed how it’s one muscle moving forward by what looks like peristaltic action. Like, guess what, my colon.
So I’m doing my Darwin thing, thinking about how I, a human was nothing but a slug wrapped in human form. Mother Nature or evolution or something decided let’s speed this dude up a bit. Let’s give him legs and arms and a brain to run the whole shebang and see what happens. I happened, albeit without the little antennae and with a chin. Slugs don’t have chins.
Slugs are a gastropod and they are slow movers. 6 1/2 inches per minute. They have one lung, one foot, and no spine. Their foot produces muscular contractions which propel this little beast if propel is the right word for such a ssslllooowww fellow. He gets there in the end.
And I got there, in the end.
