I am hoping someone may have an explanation for behaviour that I have seen exhibited by my carpet pythons for many years now.
Its like this - I enter the snake room, to see my pet pythons peacefully lying curled up below their basking lamps, and as I move closer, I occasionally notice a slight flick or twitch of the head. It is very slight - not a shiver or shake or anything that looks serious. I have seen many of my carpets do this.
Its almost as if I have disturbed their sleep or something, may be they wake up momentarily.
I am sure others have seen similar behaviour.
Can anyone offer any ideas as to why they do this?
Thanks.

Man, that is so strange! My IJ just did that a few days ago. At first I was worried that it might be neurological. It was just a quick little jerk of the head, almost like you woke him up.

wake up, maybe an interruption to their dreaming??
My carpets are the imbricata form.
I have not seen this "sleep twitch" (for want of a better term) in other python genera.
May be other keepers have?
Or maybe its a Carpet python thing?

Could be tough to tell. Fish sleep with no eyelids, and occasionally people do with their eyes open.

...in my Hognose, my Boa Constrictor, and a couple of Corns. I have never looked for any scientific data on whether or not snakes sleep. I just assumed that's what they were doing.
