Humpback whale breach sequence. A breach or a lunge is a leap out of the water, also known as cresting. The distinction between the two is fairly arbitrary: cetacean researcher Hal Whitehead defines a breach as any leap in which at least 40% of the animal's body clears the water, and a lunge as a leap with less than 40% clearance.

Several explanations for why cetaceans strand themselves have been proposed, including changes in water temperatures, [3] peculiarities of whales' echolocation in certain surroundings, [4] and geomagnetic disturbances, [5] but none have so far been universally accepted as a definitive reason for the behavior.

Others, such as the Humpback Whale (pictured), travel close to the surface and parallel to it, and then jerk upwards at full speed to perform a breach. In a typical breach, as performed by a Humpback or Right Whale , the whale clears the water at an angle of about 30° to the horizontal.
“The reason it’s been so feared over the centuries is because the Drake is where ships really have to go. Other parts (of the Southern Ocean) can be avoided.” ‘We don’t gamble’
Another humpback washed up in Napeague on Dec. 17, the group added. Authorities say the humpback whale found dead on a Long Island beach is the latest in a series of similar incidents since 2017 ...
Breaking up channels of fast-moving water allows humpbacks to retain their "grip" on the water, and turn at sharper angles even at low velocities. [ 5 ] Flippers on humpback whales ( Megaptera novaeangliae ) have non-smooth leading edges, yet demonstrate superior fluid dynamics to the characteristically smooth leading edges of artificial wings ...
