So I noticed a white thing on my tarantulas abdomin, right above the spinerettes. I first saw it like a week ago and didn't think anything of it but now its way more noticeable and I'm getting worried, it doesn't look like normal feaceas, it looks more like an object. I'll put a picture so you can see for yourself. My tarantula is a B. Smithi and is a few years old around 4'. Please respond thank you.
