Oh no you can definitely see them (pic in husbandry forum http://www.ball-pythons.net/PNphpBB2...ic-t-2677.html ). They like to get around the eyesocket because it's a much jucier meal for them there. When they get down in next to they eye you cant see them but the rim of the eye looks a little puffier or extruded (if it gets bad enough the eye almost looks sunken in).



EDIT - here are some better pics than I was able to manage: http://images.google.com/images?q=Op...ff&sa=N&tab=wi
