I'm going to start this post off with a warning to all of the arachnophobes out there, as if the post title didn't tip you off already... this post is about a speedra. I'm not great at identifying spiders, but if I had to guess, I'd say that this specimen, about the size of a US dollar coin, is some variety of wolf spider:
I didn't attempt to pick up said spider in order to determine how its eyes were arranged, nor did I shine a light on its eyes to see if it had the typical wolf spider emerald eyeshine. I'm pretty much going by size and cursorial habit.
As is typical of October weekends, I tend to post Halloween-appropriate material, and this beauty certainly qualifies as such, wolf spider or not.
