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 ...

The melon is structurally part of the nasal apparatus and comprises most of the mass tissue between the blowhole and the tip of the snout. The function of the melon is not completely understood, but scientists believe it is a bioacoustic component, providing a means of focusing sounds used in echolocation and creating a similarity between characteristics of its tissue and the surrounding water ...
Jamming occurs when non-target sounds interfere with target echoes. Jamming can be purposeful or inadvertent, and can be caused by the echolocation system itself, other echolocating animals, prey, or humans. Echolocating animals have evolved to minimize jamming, however; echolocation avoidance behaviors are not always successful.
They move echolocation to navigate and hunt and have a specialized organ in their head that changes shape to help aid in echolocation. Belugas are a noisy animals with a variety of chirps and ...
Some animals species have been taught simple versions of human languages. [6] Animals can use, for example, electrolocation and echolocation to communicate about prey and location. [ 7 ]

Although ultrasonic signals are used for echolocation by toothed whales, no known examples of ultrasonic avoidance in their prey have been found to date. [2] Ultrasonic hearing has evolved multiple times in insects: a total of 19 times. Bats appeared in the Eocene era, (about 50 million years ago); antibat tactics should have evolved then. [3]
