breeding grounds and migration routes of the humpback whale Humpback whales live along the coasts of all oceans, occasionally swimming close to shore, even into harbours and rivers. Theyundertakelong migrations between polar feeding grounds in summer and tropical or subtropical breeding grounds in wint...
Up until recently, permits to observe the humpback migration had not been provided by the researchers of the University of Cape Town. In early 2017, however, they were willing to give permits to a few filmmakers and photographers, so that the humpback whale migration could be reported world...

She added that although humpback whales' social interactions and migration patterns are very well known, little is known about their reproductive habits. There is little evidence of humpback whale penises being sighted, and their copulation has never before been recorded before the sa...
Little is known about humpback whale (Megaptera novaeangliae) dispersal and migration in the western Indian Ocean. In October 2011 and 2012, eleven satellite transmitters were deployed on wintering humpback whales from the south-western Indian Ocean breeding stock at the Comoros islands (Moh茅li, n...
. She could have been exploring new habitats, or simply have lost her way. 'We generally think of humpback whales as very well studied, but then they surprise us with things like this,’ Palacios says. ‘Undoubtedly there are a lot of things we still don’t know about whale migration....
humpbacks will slap the water vertically with their tail. The sound produced from the action can travel miles under the water, indicating that communication is quite possibly one of the purposes of this behavior. Whale biologists’ theories on the purpose of whale slapping for communication include...
This year, researchers counted more gray whale calves than in the previous few years, and the whales looked healthier during their annual migration north. Only time will tell if the population is recovering, but it seems to be on the rebound. ...
As they do, they start to demonstrate playful behavior at the surface such as breaching and tail-slapping. It is believed that this strengthens the calf in preparation for the long migration southwards; hence, the mother will permit this cavorting around while watching out for potential predators...
The humpback whale is a polygamous species. In the winter breeding season, after completing its migration, several males will surround a sexually available female and compete aggressively for the right to mate with her. Mates engage in all kinds of elaborate courtship behavior such as rolling, ...
