There have been a few 'super spiders' hatched but they do not live long enough to take their first breath because they physically can't. The Super Spider ends up as an all white snake with severely under developed lungs. Here is an article about them and a picture of an unfortunate super spider. More often than not the super spider doesn't even make it to this point of development but I would not personally breed a spider to a spider in the chance (albeit small) of ending up with one of these.
