Is it an adult? If so, this is likely the case, assuming it is female. Post a pic of it for us to evaluate.
If you're not sure if it's female, post a pic of the underside as well.
By the way, you can tell if it's an adult by the color of the telson (the tail segment bearing the sting). Brown = adult, creamy = subadult, white = juvenile. If it's fat but not an adult, it's likely nearing a molt.
