In this phase, the prey is encircled by the humpback whales and there is a 0.5% probability that either it will select a spiral model so that the position of the whales can be updated or it will choose the shrinking circling method. The behaviour can be expressed as: ...
Humpback whale, a baleen whale known for its elaborate courtship songs and displays. They usually range from 12 to 16 meters in length and weigh about 36 metric tons. The body is black on the upper surface, with a variable amount of white below, and it h
Classification of the patterns of occurrence of behaviours demonstrated that for pods both with and without calves, different units of behaviour tended to occur together when vessels were within 300 m and when they were not. Whale watching offers a nonlethal commercial use of whales, but in ...
Humpback whale vocal behaviour also varies throughout the annual cycle. Humpback whale song is produced primarily by males49,50,51and is mainly associated with reproductive behavior at low latitudes, although song also occurs regularly on foraging grounds51,52,53. Song consists of a rhythmic, repea...

Daniel Palacios, an oceanographer at the University of Hawaii at Manoa, says that the record-breaking journey could indicate that migration patterns are shifting as populations begin to recover from near-extinction and the population increases. But the reasons why the whale did not follow the usual...
A clear example of broad-scale cultural exchange among multiple populations is the transmission of humpback whale song within the South Pacific meta-population14. Song patterns are transmitted eastward from the west Australian population first to east Australia, then to New Caledonia, Tonga, and Ameri...
