Why Do Whales Breach?
Quick Fact
A humpback whale weighing 30 tonnes can launch itself almost entirely out of the water — an extraordinary feat of power requiring enormous muscular effort.
About This Species
Breaching — when a whale launches most of its body out of the water — is one of the most dramatic behaviours in the animal kingdom. Scientists have proposed several explanations: communication over long distances, parasite removal, play behaviour, or simply a display of strength. Humpback whales are among the most acrobatic, capable of launching their 30-tonne bodies almost entirely clear of the water. The exact function of breaching likely varies by species, age, and context.
Why It Matters
Understanding whale behaviour helps scientists assess population health, social structure, and the impacts of human disturbance such as vessel noise and boat traffic on these animals.
