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.
Minke whales typically live between 30–50 years, but in some cases, they may live for up to 60 years. They have a gestation and calving period of approximately 10–11 months and 2 years, respectively. [14] Minke whales have a digestive system composed of four compartments with a high density of anaerobic bacteria throughout. The presence of ...

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 ...
Humpback whale, sound spectrum and time plots. Whales occupying the same geographical areas (which can be as large as entire ocean basins) tend to sing similar songs, with only slight variations. Whales from non-overlapping regions sing entirely different songs. [12] As the song evolves, it appears that old patterns are not revisited. [12]
Both tagged Antarctic minke whales travelled in a group with the same species, ranging from 5 to 40 whales per group. Each tag recorded for 18 hours and 8 hours respectively, and during that time both whales fed continuously. 32 calls were made during this time, of which 6 had similar properties to pre-existing recordings of a bio-duck sound.
