* Specialized Anatomy: Their lower jawbone is filled with fat, which acts as a sound conductor, directing sound waves to the inner ear. This allows them to hear sounds from a much greater distance and clarity.
* Echolocation: Dolphins use echolocation, a process of emitting clicks and interpreting the returning echoes to "see" their surroundings. This ability allows them to navigate, hunt, and communicate even in murky or dark waters.
* Broad Frequency Range: Dolphins can hear sounds in a much broader frequency range than humans. Their hearing extends into the ultrasonic range, allowing them to detect high-pitched sounds that are inaudible to us.
* Sensitivity: They are highly sensitive to sound, even those at very low intensities.
* Directional Hearing: Dolphins have excellent directional hearing, meaning they can tell the direction a sound is coming from with great accuracy.
In summary: Dolphins have exceptionally acute hearing, far surpassing human capabilities, enabling them to thrive in their aquatic environment.
