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]
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 ...
Arctiid moths use a very different, but highly effective defense against bats. [21] They produce loud ultrasonic clicks in response to ultrasound. Depending on the species of moth and its ecology, the clicks may work by startling the bat, by jamming its echolocation system, or by warning of distastefulness ( aposematism ).
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
Research has recently shown that beaked and blue whales are sensitive to mid-frequency active sonar and move rapidly away from the source of the sonar, a response that disrupts their feeding and can cause mass strandings. [2] Some marine animals, such as whales and dolphins, use echolocation or "biosonar" systems to locate predators and prey.
Electroreceptive animals use the sense to locate objects around them. This is important in ecological niches where the animal cannot depend on vision: for example in caves, in murky water, and at night. Electrolocation can be passive, sensing electric fields such as those generated by the muscle movements of buried prey, or active, the ...
At the no-kill shelters The News & Observer spoke with for this story, few animals stayed on site longer than two or three months. Instead, animals that have not been adopted may be transferred to ...
River dolphins use their conical-shaped teeth and long beaks to capture fast-moving prey in murky water. They have well-developed hearing that is adapted for both air and water; they do not really rely on vision since the water they swim in is usually very muddy. Instead, they tend to rely on echolocation when hunting and
