Facts about Blue Whale Vocalization and Communication
- 05
Scientists have documented that blue whale call patterns have shifted to lower frequencies over recent decades, a phenomenon still under active research.
- 04
Male blue whales produce stereotyped, repetitive song patterns that researchers use to distinguish distinct regional populations across the world's oceans.
- 03
A blue whale's low-frequency calls can travel hundreds or even thousands of miles through the ocean, allowing communication across entire ocean basins.
- 02
Blue whale vocalizations occur at infrasonic frequencies, often below 20 Hz, making them inaudible to human ears without specialized equipment.
- 01
The calls of blue whales are among the loudest sounds produced by any animal, reaching intensities of around 180 decibels.
