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.

The killer whales regularly demonstrate their competence by chasing seals up shelving gravel beaches, up to the edge of the water. The pursuing whales are occasionally partially thrust out of the sea by a combination of their own impetus and retreating water, and have to wait for the next wave to re-float them and carry them back to sea.

Flipper movement is continuous. Some species log out of the water, which may allow them to travel faster, and sometimes they porpoise out of the water, meaning jump out of the water. Their skeletal anatomy allows them to be fast swimmers. They have a very well defined and triangular dorsal fin, allowing them to steer better in the water. Unlike ...
Researchers studying the majestic creatures have discovered the animals aren't just jumping for fun -- it's an important way to communicate. Turns out whales don't jump out of the water just for ...
Whales were intensively hunted during this time; in the 1930s, 30,000 whales were killed. This increased to over 40,000 animals per year up to the 1960s, when stocks of large baleen whales collapsed. [citation needed] Most hunted whales are now threatened, with some great whale populations exploited to the brink of extinction.
"Killer whales can easily travel 25 miles an hour," she said. "To punch a hole in the side of a dolphin and hit it so hard that it's jumping so high out of the water — the force is tremendous."
Three humpback whales jumped out of the water in unison in Cape Cod in front of stunned onlookers on Monday, 24 July. Extraordinary footage captured by Robert Addie shows the huge creatures ...
As whales reach the water surface to breathe, they forcefully expel air through the blowhole. The exhalation is released into the comparably lower-pressure, colder atmosphere, and any water vapor condenses. This spout, known as the blow, is often visible from far away as a white splash, which can also be caused by water resting on top of the ...
