The Anatomy of Betta Fish Ears:

Let me tell you about Betta fish anatomy and how they perceive sound in their environment. Unlike humans with external and visible ears, Betta fish have internal ears behind their eyes. Betta fish ears consist of three parts: the outer ear, the middle ear, and the inner ear.

The Outer Ear:

The outer ear is located at the base of the operculum, the bony plate that covers and safeguards their gills. The auditory meatus, a small opening, is present in the outer ear, allowing sound to enter the ear canal. The shape of the operculum is such that it directs the sound toward the ear canal, which is short and narrow.

The Middle Ear:


Moving on to the middle ear consists of a thin membrane called the tympanic membrane. This membrane separates the outer ear from the inner ear. The tympanic membrane vibrates in response to sound waves and passes them on to the inner ear.

The Inner Ear:


Finally, the inner ear contains the cochlea, which converts sound vibrations into electrical signals the brain can understand. The cochlea is a spiral-shaped structure lined with tiny hairs that detect sound vibrations. When the hairs in the cochlea vibrate, they generate electrical signals that travel through the auditory nerve to the brain. And that’s how Betta fish hear the sounds in their surroundings.

How Betta Fish Ears Differ from Human Ears:

Allow me to elucidate the differences between Betta fish ears and human ears:

  • Betta fish ears are internal, whereas human ears are external and visible.
  • Reflecting their smaller body size, Betta fish ears are much smaller than human ears.
  • Betta fish ears have a more straightforward structure than human ears, reflecting their simpler hearing abilities.

A significant difference between Betta fish and human ears lies in the frequency range they can detect. Human ears can detect sounds between 20 Hz to 20,000 Hz, while Betta fish can only detect sounds between 50 Hz to 4,000 Hz. This implies that Betta fish are less sensitive to high-pitched sounds than humans but more sensitive to low-pitched sounds.
