Why do whales breach and jump out of the water?
Whales breach and jump out of the water for many reasons, but one main reason is that whales can jump to make an extra loud sound effect.

This is beneficial for whales striving to communicate with other whales who may be located long distances away.
Do whales ever breach under a boat?
Why do whales breach near boats? As breaching is often seen in rough seas it is possible that a breach allows the whale to breathe in air that is not close to the surface and full of spray, or that they use breaching to communicate when the noise of the ocean would mask acoustic signals.
Do all whales have a blowhole?
All whales have one or two blowholes on top of their heads. This organ started out as a nostril-like feature at the tips of the snouts of whales that lived millions of years ago. Over time, those nostrils slowly moved backwards to the top of a whale’s head. This allowed the animals to breathe by skimming the surface of the water.

The whale may land on its side or back ...
How do whales keep an eye on their surroundings?
One common method for keeping an eye on their surroundings is spy-hopping, where the whale lifts itself partially above the water to get a good look at its surroundings. Spy-hopping is less dramatic and exposing than breaching, but it may be an effective method for observing their environment when combined.
