Most toothed whales use clicks in a series, or click train, for echolocation, while the sperm whale may produce clicks individually. Toothed whale whistles do not appear to be used in echolocation. Different rates of click production in a click train give rise to the familiar barks, squeals and growls of the bottlenose dolphin. A click train ...
The mechanism requires two molecules, each with unpaired electrons, at a suitable distance from each other. When these can exist in states either with their spin axes in the same direction, or in opposite directions, the molecules oscillate rapidly between the two states. That oscillation is extremely sensitive to magnetic fields.
Biocommunication of animals may include vocalizations (as between competing bird species), or pheromone production (as between various species of insects), [4] chemical signals between plants and animals (as in tannin production used by vascular plants to warn away insects), and chemically mediated communication between plants [5] [6] and ...
Animal echolocation, animals emitting sound and listening to the echo in order to locate objects or navigate; Echo sounding, listening to the echo of sound pulses to measure the distance to the bottom of the sea, a special case of sonar; Gunfire locator; Human echolocation, the use of echolocation by blind people; Human bycatch
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 ...
The sounds animals make are important because they communicate the animals' state. [5] 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]
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 moth Bertholdia trigona is one of several moth species known to jam the echolocation of its predator. Many tiger moths produce ultrasonic clicks in response to the echolocation calls bats use while attacking prey. [11] For most species of tiger moth these clicks warn bats that the moths have toxic compounds that make them distasteful. [12]
