An important finding is that whales, in a process called the Lombard effect, adjust their song to compensate for background noise pollution. [46] Blue whales stop producing foraging D calls once a mid-frequency sonar is activated, even though the sonar frequency range (1–8 kHz) far exceeds their sound production range (25–100 Hz). [2]
The sperm whale's vocalizations are all based on clicking, described in four types: the usual echolocation, creaks, codas, and slow clicks. [126] The usual echolocation click type is used in searching for prey. [126] A creak is a rapid series of high-frequency clicks that sounds somewhat like a creaky door hinge.
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. When the information from the sender changes the behavior ...
The buoys recorded whale vocalizations, known as songs, researchers said. The recordings of the whale songs were transmitted back to acousticians, who interpreted the audio in real time.
Whales: Two groups of whales, the humpback whale and a subspecies of blue whale found in the Indian Ocean, are known to produce repeated sounds at varying frequencies, known as whale songs. Male humpback whales perform these vocalizations only during the mating season, and so it is surmised the purpose of songs is to aid sexual selection ...
The basic functions of communication in aquatic animals are similar to those of terrestrial animals. In general, communication can be used to facilitate social recognition and aggregation, to locate, attract and evaluate mating partners and to engage in territorial or mating disputes. Different species of aquatic animals can sometimes communicate.
Whistling is a minor component of southern resident orca vocalizations, "whereas whistles are the primary social vocalization among the majority of Delphinidae species." [ 72 ] [ 73 ] The pulsed calls of orcas may sound to humans like forms of speech, music, or wordless squeals, [ 74 ] [ 75 ] "with distinct tonal qualities and harmonic structure.
Toothed whale. The toothed whales (also called odontocetes, systematic name Odontoceti) are a clade of cetaceans that includes dolphins, porpoises, and all other whales with teeth, such as beaked whales and the sperm whales. 73 species of toothed whales are described. They are one of two living groups of cetaceans, the other being the baleen ...
