What is the gullet frog?

What is the function of the Eustachian tube?
This air-containing space is maintained by the Eustachian tube, which opens intermittently to equalize the intratympanic air pressure with the pressure in the external auditory canal. It also removes secretion and epithelial debris from the middle ear by ciliary motion and gravity.

How do frog ears work?
Despite looking a lot different from our own, frogs' ears work in a surprisingly similar way! As sound waves are picked up by the frog's tympanum, it vibrates. The tympanum then transports the sounds and vibrations to the middle ear. The middle ear amplifies the sounds and sends them to the inner ear.
Where are the Eustachian tubes?
The eustachian tube is a canal that connects the middle ear to the nasopharynx, which consists of the upper throat and the back of the nasal cavity. It controls the pressure within the middle ear, making it equal with the air pressure outside the body.

What is special about frog ears?
Another cool fact about frogs and toads is that they have ears. They don't have lobes like us but instead have external ear drums, called tympanum. The tympanum is a ring of thin skin that can pick up vibrations. It is important for them to hear, because they call to each other.
