I was just returning to my office a few minutes ago and one of the other faculty members who shares this corridor was calling “There’s a snake in here.” I rounded the corner, and she was just outside my office looking down at what was clearly a juvenile snake of some sort.
My first thought was that it was probably a garter snake of some sort. When we lived in Baltimore, i caught a few garter snakes in our backyard. My first inclination was to simply pick it up and take it outside.
But when i got closer, it coiled up into a defensive posture, reared its head up, and began striking. I’ve never seen a garter snake do that—in my experience, they usually try to get away as quickly as they can—and i also remembered that i’m now living in the southwest, a place with its fair share of venomous snakes.
So i grabbed the glass container that i brought my lunch in, along with the lid, and after a bit of maneuvering managed to capture it. After i caught it, the little bugger continued to strike at me through the glass of the bowl in the manner of a venomous snake, and as i type this he (or she) is still curled in a defensive position staring intently at me.
Unfortunately, i have no camera with me, so i can’t take a picture of it for ID purposes. I’ve been looking at the range maps on this page, and checking out all the snakes that can be found in the San Diego area (the university is in San Marcos, in the north part of San Diego County) but haven’t really found a completely convincing match. One problem is that most of the pictures are of adults, and i’m pretty sure i have a juvenile here (it’s only about 6-7 inches long, and less than a half-0inch thick at its thickest point).
The marking is a sort of dark-brown diamond-shaped pattern that extends over the back of the snake. This is laid over a very light brown. Looking at the snake’s body side-on, it looks like a series of upside down brown triangles, with rightside-up triangles filling the gaps between the downward-pointing marks. If that makes sense.
Of the snakes i’ve found, the pattern is closest, i think, to some of the lyresnake patterns on this page. In terms of the shape of the markings, this guy is probably closest (and the striking position that mine is adopting is also almost identical to the one in this image), but my snake is nowhere near as red in color; mine is more clearly dark brown over light brown or grey, like this one.
