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.

It might be that killer whales have learned to stay away from shallow waters, and that heading to the shallows offers the smaller animals some protection from predators. However, killer whales in Península Valdés , Argentina, and the Crozet Islands in the Indian Ocean have learned how to operate in shallow waters, particularly in their ...
Sperm whales have the largest brain mass of any animal on Earth, averaging 8,000 cm 3 (490 in 3) and 7.8 kg (17 lb) in mature males. [24] The brain to body mass ratio in some odontocetes, such as belugas and narwhals, is second only to humans. [25] In some whales, however, it is less than half that of humans: 0.9% versus 2.1%.

The mystery as to why a beluga whale appeared off the coast of Norway wearing a harness may finally have been solved. The tame white whale, which locals named Hvaldimir, made headlines five years ...
Whales, dolphins used since the Cold War The use of marine animals for military purposes traces back to the Cold War as both the U.S. and U.S.S.R. used dolphins to protect ships and harbors as ...
A researcher fires a biopsy dart at an orca.The dart will remove a small piece of the whale's skin and bounce harmlessly off the animal. Cetology (from Greek κῆτος, kētos, "whale"; and -λογία, -logia) or whalelore (also known as whaleology) is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoises in the scientific ...

Research has recently shown that beaked and blue whales are sensitive to mid-frequency active sonar and move rapidly away from the source of the sonar, a response that disrupts their feeding and can cause mass strandings. [2] Some marine animals, such as whales and dolphins, use echolocation or "biosonar" systems to locate predators and prey.
