Ontogeny and synchrony of diving behavior in Humpback whale mothers and calves on their breeding ground
Abstract For humpback whales, the mother–calf pair is the only stable social unit with calves following their mother after birth and staying in close proximity. This following strategy ensures the maintenance of such close proximity between the mother and her calf, with calves benefiting from matern...
