Whale vocalizations are the sounds made by whales to communicate. The word "song" is used in particular to describe the pattern of regular and predictable sounds made by some species of whales (notably the humpback and bowhead whales) in a way that is reminiscent of human singing. Humans produce sound by expelling air through the larynx.
There are at least nine separate blue whale acoustic populations worldwide. [41] Over the last 50 years blue whales have changed the way they are singing. Calls are progressively getting lower in frequency. For example, the Australian pygmy blue whales are decreasing their mean call frequency rate at approximately 0.35 Hz/year. [42]
It is one of Earth's most haunting sounds - the "singing" of baleen whales like the humpback, heard over vast distances in the watery realm. Baleen whales - a group that includes the blue whale ...
“The blue whale is the largest and loudest animal on Earth.” The blue whale is the largest animal on Earth and likely the largest animal ever to have lived. While this ocean mammoth is dubbed ...
Whales range in size from the 2.6-metre (8.5 ft) and 135-kilogram (298 lb) dwarf sperm whale to the 34-metre (112 ft) and 190-metric-ton (210-short-ton) blue whale. Overall, they tend to dwarf other cetartiodactyls; the blue whale is the largest creature on Earth.
Before extensive research on whale vocalizations was completed, the low-frequency pulses emitted by some species of whales were often not correctly attributed to them. Dr Payne wrote: "Before it was shown that fin whales were the cause [of powerful sounds], no one could take seriously the idea that such regular, loud, low, and relatively pure frequency tones were coming from within the ocean ...
For example, a blue whale can communicate with another blue whale using sound over thousands of miles across the sea. [6] 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]
All baleen whales use sound for communication and are known to "sing", especially during the breeding season. Blue whales produce the loudest sustained sounds of any animals: their low-frequency (infrasonic, under 20 Hz) moans can last for half a minute, reach almost 190 decibels, and be heard hundreds of kilometers away. Adult male humpbacks ...
