A humpback whale breach is a spectacular and breathtaking behavior commonly observed in humpback whales. This behavior involves the whale propelling itself out of the water and into the air, often twisting or rolling as it does so. There are several reasons why humpback whales breach, although the exact motivations are not fully understood. Some potential reasons include:

Communication: Breaching may serve as a form of communication between whales. The loud splash and sound produced when a humpback whale breaches can be heard over long distances underwater, and this may help convey information to other whales in the area. Parasite removal: Breaching could help dislodge parasites, barnacles, or other organisms that attach themselves to the whale's skin. The force of hitting the water may help in removing these unwanted hitchhikers.
