What is it about snakes?

This morning, my wife took a picture of a snake she saw when walking the dog – it was sitting next to the raised bed where we have strawberries. She posted it on facebook and I re-shared it, adding the caption “This is my friend Sam. He keeps the field mice out of my garden. Sam loves us because we don’t stir our compost very often and attract a lot of food for him.”
Being a parent, and largely ignorant about snakes, the first thing I did was try to look him up and make sure he wasn’t venomous. Indiana only has a few venomous snakes – cottonmouths, copperheads, and a couple of different rattlesnakes. Sam didn’t fit any of those, but then my curiosity got the better of me and I started hunting around the internet. I looked at probably two dozen species of snakes that I found on various websites purporting to identify the common snakes of Indiana. I spent maybe 30 minutes and came up empty handed but with a few things that were “kinda” close. I sent the picture to a local herpetologist, Jim Horton of the Hoosier Herpetological Society and, I learned, of Indiana Jim’s Reptile Experience, and he got back to me in less than an hour, saying “The snake in question is an eastern garter snake. They are very common in Indiana (not to mention harmless).”
Finished with that, I jumped back on my facebook page and had all sorts of comments and messages from friends and family. Some were excited and others were concerned that the snake might be venomous. Truthfully, I was surprised at how may people were interested in one way or another, and also a little touched that so many people were concerned. But it made me wonder – what is it about snakes that inspires this fascination? People who know snakes know that there are a lot more around than most people would ever believe. I remember preparing for a camping trip in the Red River Gorge and reading somewhere that at any point along the trail there are statistically at least 10 snakes within a 10 meter radius of you.
I’m not afraid of snakes personally. I actually want the right kinds of snakes in my garden, as my caption above suggests. I don’t love them either. I guess I’m somewhere in the middle. I don’t want one as a pet and I tend to steer clear of them, but as a runner, I’m far more afraid of stray dogs in my neighborhood. Still, almost everyone I know gets extremely anxious about snakes, far more than I’d expect simple unfamiliarity to cause.
So I thought I’d explore the psychology behind the way people react to snakes – here are a few of the interesting things I found:
- Wikipedia says that the abnormal fear of snakes is called ophidiophobia. Most people, even the ones who really don’t like snakes, don’t suffer from this. Phobias are far more intense than a simple aversion.
- As reported here, a recent study suggests that humans may be genetically hard-wired to fear snakes and earlier studies suggest that our brains actually react to the sight of a snake before we even have time to consciously identify it as a snake. The link contains some speculation about why – but it’s just speculation.
- Predictably, other experiments suggest it’s a learned behavior and interestingly, even at 11 months old, boys and girls react differently to seeing snakes.
- Another interesting thing – learned by comparing both of the above links is that humans seem to be fairly perfectly evolved to pick out a snake in hiding. Even very young children, shown pictures of snakes in various settings pick out the snake before anything else in the picture.
- And here is a lot more info about the Eastern Garter Snake. Admittedly, the pics look a bit different than the one we took – but the professional herpetologist was quite certain, so I’m going to defer to his judgment. Also, if you look here the picture in the lower right shows a juvenile Eastern Garter snake and that one looks a lot more like Sam.
I found them interesting anyway – hopefully some of you out there in internet land will as well. I guess if you really look at it, it boils down to no one knows why we are afraid of snakes but to greater and lesser degrees, we are.
