The term echolocation was coined by 1944 by the American zoologist Donald Griffin, who, with Robert Galambos, first demonstrated the phenomenon in bats. [1] [2] As Griffin described in his book, [3] the 18th century Italian scientist Lazzaro Spallanzani had, by means of a series of elaborate experiments, concluded that when bats fly at night, they rely on some sense besides vision, but he did ...
Principle of bat echolocation: orange is the call and green is the echo. In low-duty cycle echolocation, bats can separate their calls and returning echoes by time. They have to time their short calls to finish before echoes return. [95] The delay of the returning echoes allows the bat to estimate the range to their prey. [93]

Additionally, echolocation allows the odontocete to easily discern the difference between objects that are different in material composition, even if visually identical, by their different densities. Individuals also appear to be able to isolate their own echoes during pod feeding activity without interference from other pod members' echolocations.
In 2014 Liu and others delved into the evolutionary adaptations of Prestin, unveiling its critical role in the ultrasonic hearing range essential for animal sonar, specifically in the context of echolocation. This adaptation proves instrumental for dolphins navigating through turbid waters and bats seeking sustenance in nocturnal darkness.
Echolocation is the process where an animal produces a sound of certain wavelength, and then listens to and compares the reflected echoes to the original sound emitted. Bats use echolocation to form images of their surrounding environment and the organisms that inhabit it by eliciting ultrasonic waves via their larynx .
