The burmese have these too, but they seem to be either in the middle of evolving, or remnants of heat pits they had eons ago but which have all but disappeared. The burmese have 6 or 7 on their lower jaw, toward the rear of their jaw. The rocks have 3 or 4 well defined pits in this same area, and undoubtedly still functional. The number on either side can be irregular. I thought you had a burmese Skin. Aren't you that guy from Holland with a fairly large female?
:I have noticed that my rock has also 2 heatpits in the corner of his mouth in the lower jaw.. is this also with burms??? :who can tell me :) :
