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 ...

Examples include echolocation of bats and dolphins and insect antennae. Using self-generated energy allows more control over signal intensity, direction, timing and spectral characteristics. By contrast, passive sensory systems involve activation by ambient energy (that is, energy that is preexisting in the environment, rather than generated by ...
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]
Animal communication is a rapidly growing area of study in disciplines including animal behavior, sociology, neurology, and animal cognition. Many aspects of animal behavior, such as symbolic name use, emotional expression, learning, and sexual behavior , are being understood in new ways.
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 (sound navigation and ranging), the use of sound on water or underwater, to navigate or to locate other watercraft, usually by submarines.
Located in Seward, there’s a range of marine animals, birds, fish, and invertebrates to become acquainted with at Alaska SeaLife Centre. For example, there are sea lions, ringed seals, spotted ...
