While terrestrial animals often have a uniform method of producing and detecting sounds, aquatic animals have a range of mechanisms to produce and detect both vocal and non-vocal sounds. [7] In terms of sound production, fish can produce sounds such as boat-whistles, grunts and croaks using their swim bladder or pectoral fin.
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
Whales use a variety of sounds for communication and sensation. [1] The mechanisms used to produce sound vary from one family of cetaceans to another. Marine mammals, including whales, dolphins, and porpoises, are much more dependent on sound than land mammals due to the limited effectiveness of other senses in water.
While cicadas are well-known for sound production via abdominal tymbal organs, it has been demonstrated that some species can produce sounds via stridulation, as well. [9] Stridulation is also known in a few tarantulas (Arachnida), certain centipedes, such as Scutigera coleoptrata, and some pill millipedes (Diplopoda, Oniscomorpha). [10]
Many animals produce sound to communicate with each other, and bats are no exception. They can produce a range of frequencies, also known as the vocal range, that far exceeds vertebrates including ...
The examples include ground vibrations produced by elephants whose principal frequency component is around 15 Hz, and low- to medium-frequency substrate-borne vibrations used by most insect orders. [14] Many animal sounds, however, do fall within the frequency range detectable by a human ear, between 20 and 20,000 Hz. [15]
The ampullae detect electric fields in the water, or more precisely the potential difference between the voltage at the skin pore and the voltage at the base of the electroreceptor cells. [11] [12] [6] A positive pore stimulus decreases the rate of nerve activity coming from the electroreceptor cells, while a negative pore stimulus increases ...
