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.

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 ...
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.

New estimate for endangered right whale population in 2023 shows a slight increase, but scientists fear it could be temporary after a deadly 2024
A group of researchers that studies the whales said Tuesday that the population increased to an estimated 372 in 2023. That's an increase of about 4% from 2020, and “heartening news” after the whale's population fell by about 25% from 2010 to 2020, researchers said in a statement.
