How do snake hear?
The middle ear contains three bones that transmit sound from the eardrum to the inner ear via vibrations. The inner ear turns these vibrations into nerve impulses that travel to the brain. This enables snakes to hear vibrations, such as a predator creeping closer on the forest floor.
How good can snakes hear?
Snakes lack external ears (pinna), ear canals (external auditory meatus) or external ear drums (tympanic membrane) as is seen in most other reptiles, but they have well-developed internal ears and can hear sounds from 40 to 2,000 hertz; the human voice averages 500 to 1,000 hertz, and thus, is within the range of …
What causes a snake to fart?
Snakes will pass air they may build up, assuming this is the case, snakes are capable of “farting”, but this is a little different from a snake than it would be from any other animal. Due to flatulence is a build-up of gas that is released by bacteria feeding on the gut contents to create the “snake fart” build up.
How is it possible for a snake to hear?
It is believed this is possible because of spinal nerves that conduct vibrations from the skin. This type of hearing is known as somatic hearing. Just like the ears of other animals, the vibrations are sent through the bones to the inner ear and transmitted to the brain as signals where they are interpreted as sound. What Snakes Can Hear?
How does a snake detect an airborne sound?
Thus, like many other animals, snakes have two ways of detecting sounds: earthborne and airborne. The earthborne vibrations are passed through the belly muscles to special receptors along the spine and thus transmitted to the brain. Airborne sounds are transmitted to the lung from the skin receptors to the eighth cranial nerve and inner ear.”
How is the pitch of sound measured in snakes?
As with other animal ears, this movement is transferred (via bones) to the inner ear and then signals are sent to the brain and interpreted as sound. Pitch (high or low sounds) is measured in Hertz (Hz) and how quiet or loud sounds are is measured in decibels (dB).
What kind of ear does a snake have?
In the “Ask the Experts” column, Winston Card responds to a snake hearing question by explaining that, while snakes lack external and middle ear structures (including the tympanum, or ear drum), they do have inner ear structures which have been shown experimentally to receive airborne sound waves.

What kind of music does a snake listen to?
“The movement of the snake is completely keyed in on the guy playing the toodley thing,” says Robert Drewes, chairman of the department of herpetology (the study of amphibians and reptiles) at the California Academy of Sciences in San Francisco. “He sways, the snake sways.”
Where does a snake get its vibrations from?
The snakes’ jawbone transmits the vibrations to their inner ears which then signal their brains. Additional research is required to detect the variance in the abilities of different snake species to detect vibrations.
Why does a snake not respond to sound?
The snakes don’t seem to be responding to vibrations that these sounds cause in the ground, since these vibrations were too weak to cause nerve activity when they weren’t accompanied by sound in the air, Christensen and his colleagues found.
