Could be a number of reasons why they are different. Could just be different photo angles, my snakes pits may look smaller because it has a larger head or it could just be as simple as natural variation between the snakes. To be honest there is probably no real 100% answer to the question.Really nice snake mate, can i ask why my bredli's heat pits are longer and deeper? iv got a couple of pics if you can see what i mean
