Many reasons have been suggested for breaching. Whales are more likely to breach when they are in groups, suggesting social reasons, such as an assertion of dominance, courting or warning of danger. It is also possible that the loud “smack” upon re-entering is useful for stunning or scaring prey. Others suggest that a breach allow the whale to breathe in air that is not close to the surface, which may aid breathing in rough seas. Another widely accepted possible reason is to dislodge parasites from the skin. But to tell truth I do not think the guests I have in the boat care about the reason they are just happy to see breaching whales.
