This is because periods with highest acoustic presence of Antarctic minke whales aligned with their breeding season at lower latitudes of the Antarctic Ocean. [5] Additionally, the bio-duck sound shared similar acoustic properties to a "pulse train" which is another call by minke whales believed to serve reproductive functions. [6]

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.

Humans produce sound by expelling air through the larynx.
