Why do whales breach the water?

Whales breach the water for a variety of reasons, including communication, hunting, and social interaction. Breaching, which involves leaping out of the water and crashing back down, can create loud sounds that help whales communicate with others over long distances. It may also help them shake off parasites or clear their blowholes. In some species, like humpback whales, breaching is a form of display, possibly to attract mates or establish dominance. This behavior is also a way for whales to exercise their muscles.
