I’ve been savoring this lovely used book I picked up a little while ago, The Book of Spiders and Scorpions by Rod Preston-Mafham, and am appreciating more than the fact that it is full of beautiful photography of spiders and lots of general information on arachnid behavior and physiology; it’s also true that spiders are awfully sexy beasts. They are playful and romantic and kinky and enthusiastic and ferocious and savage and exotic, and really know how to have a good time. I thought I’d share a few of the pretty pictures and details of the arachnid sex life with the readers of Pharyngula—so if you’re mature enough to handle it, exuberant enough to enjoy reading about interesting animals doing fun things, and aren’t too squicked out at the idea of closeups of spider genitalia, read on.
