Where did you hear this? Do you mind sharing this documentation?
Spider is a dominant trait. Unless it is a visual Spider, you don't have the Spider gene in your normal ball python. There are other morphs associated with a wobble (Champagne, HGW, Powerball, Super Sable, Woma), but again, the genetic wobble only occurs in the visual animals.
You mentioned your temperatures and what you are using to measure them, but you didn't say what device (heat tape, heat pad, heat bulb, heat rock, etc) you are using to reach these temperatures. Also, what kind of digital thermometer? Is it the kind with a probe on it? If so, where is that probe placed? Perhaps a picture would help if you could do so.![]()
