Today when I was handling my emperor scorpion, I felt something itchy on it, and sure enough I noticed what looked to be something similar to urticating tarantula hairs, except they don't dislodge. I've seen these before on it, but for some odd reason, it looked bigger this time. I believe they are used for sensing prey. Are they similar to tarantula urticating hairs? Are they made of the same material as the exoskeleton?
