A blue whale's song is composed of repeated stereotyped units called phrases, which are arranged into longer patterns known as themes or song types.
- 05
Researchers have documented that blue whale call patterns have shifted to lower frequencies over recent decades, a phenomenon still under scientific investigation.
- 04
Male blue whales are the primary producers of vocalizations, which are thought to play a role in mating and social communication.
- 03
Different populations of blue whales produce distinct regional call types, allowing scientists to identify and track separate groups across ocean basins.
