Do snake have ears?

SnakeWhenever we see snakes and when we notice their rapid movements there is one question that comes in our minds that whether snakes have ears or not? But this was one of the long-term myths that snakes are deaf and they cannot hear anything only the movement on the grounds can be sensed by them. But these points are no more exist able when it comes to rattle snakes where they can hear the rattling noise made by their tails.

A deep study has been carried out on this topic and analyses are made which proves that snakes do have internal ears and they can hear as well. Bruce Young is one of the neurobiologists and he made some new researches which can prove the mentioned points.

How humans inner ears are different from that of snakes? Human ears consists of several parts such as hair cells, bones and ear drum when there are sound waves that causes vibrations of tiny hair cells due to small movement of bones because of sound waves that hits the eardrum. These vibrations then reaches to the brain in the form of nerve impulses and this make us to hear the sounds. On the other hand snakes lacks these year drums and have totally different inner ear structures according to which their jawbone have a direct connection with their inner ears and the movements on the ground are received by their brain in the form of signals through their inner ears.

This study made it clear that snakes can also hear the movements made on the ground but whether they can hear to the air travelling sounds where the medium is air. Another biologist with a name Christian Christensen of Aarhus University in Denmark along with few of his colleagues made a study on the ball python. By attaching the electrodes to pythons head a study was made on their inner ears neurons that connect them to their brain and their nerve pulses were recorded with results of frequency lying between 80 t0 100 hertz. The study was successful but since there are almost 3000 varieties of snakes and each one is different from the other in various prospects.
