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 ...
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).

Animal echolocation, non-human animals emitting sound waves and listening to the echo in order to locate objects or navigate. Human echolocation , the use of sound by people to navigate. Sonar ( so und n avigation a nd r anging), the use of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines.
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 ...
Several explanations for why cetaceans strand themselves have been proposed, including changes in water temperatures, [3] peculiarities of whales' echolocation in certain surroundings, [4] and geomagnetic disturbances, [5] but none have so far been universally accepted as a definitive reason for the behavior.
