Jen, I need you to help me understand your theory. Snakes can't hear airborne sounds...

They CAN hear airborne sounds, actually, they're just not as sensitive to it as we are.

As a couple of examples. Just because ball pythons in particular have not been studied does not mean they can't hear sound. They also perceive it differently; again, since they haven't been studied in particular, who's to say they don't use their head in some way to perceive sound?

I was merely offering it as one of many possibilities, not saying that for sure is why the snake is moving its head.

No not a spider but i did wonder if it was possible for her to have a resessive spider gene so i looked up the wobble on youtube. Its nothing as dramatic as that. Its just a gentle swaying from side to side and only when she is waiting to strike.

Your own source material states that the auditory system in Boidae (most similar to Pythonidae) is limited to a range band of 150 Hz to 600 Hz, and that there is a U-shaped curve along that range where there is a distinct, best frequency....In humans and mammals, we would identify that range of hearing as being effectively deaf.

I have done anecdotal testing with my own animals, and I can assure you that my BPs do not react to airborne sounds higher on the frequency range than those which can be felt through their jaw bones i.e. very low frequency.

That first link is from a paper published in the 1970's.

Check the second paper.

"This study provides the first experimental evidence that snakes can respond behaviourally to airborne sounds."

-Jen

I did read the second study report, which states that snakes can only percieve sounds up to 450 Hz, effectively rendering them even deafer than those in the first study you sited.

I still stand by my observations.

Please feel free to believe anything you wish, however, I would urge you to maybe do some experimentation of your own, with your own animals.

It's not that I automatically distrust scientific journal results, it's just that often times they are not searching for the same answers I am. Different expectations often arrive at different results.

So I'm confused. Are you guys saying that my bp is or is not moving her head in an attempt to hear?

It's probably not an attempt to hear. I was throwing it out there as one of a myriad of possibilities. :)

For the record, I am not saying your BP is moving her head in am attempt to hear.

So what your saying is, ball pythons can hear? :p

I remember reading somewhere that animals with eyes on the sides of their heads sometimes move side to side for depth perception.
