I checked a couple of mine, pretty cool, i never took any notice of it before.
Not very big and it's in a bad place if they where using it for hunting.
Maybe it's something to do with regulating or knowing their body temp as they use their heads to warm up alot of the time.
Very interesting, i'm sure there will be some good debates as to what is used for.
I personally can't see how it would be good for hunting, it's quite consealed it would be dragging the ground, heat trails? Other pythons are pointing straight out.
Have you ever noticed when bhps get excited or are in a new place they make a sort of head bobbing motion, could be exposing the pit...... i'm crapping on now
