High Quality Content by WIKIPEDIA articles! Whales exhibit various types of behaviour when they surface.

Qualitatively, a breach is a genuine jump with an intent to clear the water, whereas a lunge is the result of a fast upward sloping swim, perhaps as a result of feeding, that has caused the whale to clear the surface of the water unintentionally.
