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.

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]
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.

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 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 ...
Whales sing loud enough that their songs travel through the ocean, but knowing the mechanics behind that has been a mystery. Scientists now think they have an idea, and it's something not seen in ...
Whales vary the noises they make and Parks' research has described the soft sounds used by mother and calf pairs as 'whispers' which may avoid the unwanted attention of predators. [15] [16] The clock-like sounds in humpback whales could be a signal to nearby whales about the presence of food or a means to get the whales' prey to come out of the ...
For a supposed spy, Hvaldimir was anything but covert. The white beluga whale had appeared regularly along the coast of Norway since it was first spotted in the country’s north in April 2019 ...
