OK, I’m trying to parse these images, but any spider limb diagram that incorporates the abdomen doesn’t work. The coxa (the proximate segment of the limb) attaches to the cephalothorax, not the abdomen, so the first two images simply do not fit. The third, maybe, but only if the pants hang so low they don’t cover the coxa, trochanter, and femur.
Maybe this diagram of the ventral cephalothorax will help.
I’m sorry if my pedantry ruins the joke, but spiders wouldn’t wear pants.
