Does snakes have some kind of inner ears?
Answers:
Yes, they don't have an ear like what is on the side of your head, but they do have a tympanic membrane-an ear drum.
They have little slits and those are what they hear out of. Like on a turtle.
no
Yes, it detects vibrations.
Yes!
no...they sense movement and heat with their tongues
Yes. they can't hear like mammals do though, but they can sense vibrations.
Some also have pit organs that sense heat, but they're only found in the western part of the world, like North ans South America, the rattle snake is an example. Snakes and other reptiles also have a Jacobson's organ.
They have a little pinhole in the sides of their head. They can even hear someone talking in a normal voice 10 feet away in a quiet room!
Snakes DO have well-developed inner ears, with which they can detect even slight vibrations through solid surfaces, like the ground, and with which they can maintain a sense of balance. Snakes do NOT, however, have any external ear openings whatsoever-no "little pinholes", no "little slits", nothing, so please disregard those badly-informed individuals who claim otherwise! Snakes also do not have an eardrum, or tympanic membrane, and study after study has proven that snakes have no ability to hear sound waves carried through the air. They are, for all practical purposes, deaf, and the only group of vertebrates that does not use sound at all to communicate with one another. Snakes MIGHT, however, be able to sense some frequencies of airborne sound waves not via their ears, but through highly-sensitive nerve endings in their skin and muscles, as some experiments suggest. I've kept snakes since childhood, of many species, and I've never seen any response to airborne sound at all from any of them.
