Corn snakes are completely docile and it is very unlikely for one to bite, but anything with a mouth bites. To me it seems that very rarely will a Corn snake ever bite you defensively. I have a Kingsnake, and only have been bitten once by him, but that was a simple feeding response and I do not blame him for that, it was my mistake. Corn snakes are curious and adventurous so they do slither around a lot, but don't seem to mind being handled.
