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.

An important finding is that whales, in a process called the Lombard effect, adjust their song to compensate for background noise pollution. [48] Blue whales stop producing foraging D calls once a mid-frequency sonar is activated, even though the sonar frequency range (1–8 kHz) far exceeds their sound production range (25–100 Hz). [2]
Whales can communicate through sounds ranging from clicks, whistles and pulsed calls. These loveable creatures are highly social and travel in groups called 'pods'. Killer whales have no predators ...
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 ...
Even the long tusk of the narwhal is a vice-formed tooth. In many toothed whales, the depression in their skull is due to the formation of a large melon and multiple, asymmetric air bags. [citation needed] River dolphins, unlike most other cetaceans, can turn their head 90°. Most other cetaceans have fused neck vertebrae and are unable to turn ...
A male humpback whale made one of the longest and most unusual migrations on record for the species, an anomaly scientists say might be linked to climate change.
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 ...
