Using echolocation, bats can determine how far away an object is, the object's size, shape and density, and the direction (if any) that an object is moving. Their use of echolocation, along with powered flight, allows them to occupy a niche where there are often many insects (that come out at night since there are fewer predators then), less ...
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 ...
The use of mechanosensitive hairs is homologous to the functioning of hair cells in the auditory and vestibular systems, indicating a close link between these systems. [12] Due to many overlapping functions and their great similarity in ultrastructure and development, the lateral line system and the inner ear of fish are often grouped together ...
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 ...
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.
In animals, motion is typically achieved by the use of skeletal muscles, which derive their energy from the metabolism of nutrients from food. [2]: 406 Because these muscles are attached to both of the components that must move relative to each other, they are not capable of directly driving a wheel, and can only do so through a linkage. In ...
Ultrasound avoidance is an escape or avoidance reflex displayed by certain animal species that are preyed upon by echolocating predators. [1] Ultrasound avoidance is known for several groups of insects that have independently evolved mechanisms for ultrasonic hearing.
Through this experiment, Moby Doll was the first to give proof of the use of echolocation by orcas. [ 10 ] [ 7 ] Furthermore, by comparing Moby Doll's orientation with the sound characteristics of the click recordings, the scientists demonstrated the sharp, directional nature of his echolocation, giving support to Kenneth Norris's new ...
