That would depend on what species it is, though. Some species (like Black Racers) are going to look the same in pics. Plus, it's way easier to have a specific spot on the snake to check for some kind of mark, than to try and compare photos with totally different backgrounds to see if the pattern looks similar or not...

I don't want something that is completely permanent, but I don't want something that is going to disappear after the first shed.
