A new case of interoceanic movement of a humpback whale in the southern hemisphere: The El Niño Link
Extensive seasonal migrations by humpback whales (Megaptera novaeangliae) have been well documented for decades. Unlike other more oceanic whales with complex seasonal patterns, such as blue (Balaenoptera musculus), sei (B. borealis), and even Bryde's (B. edeni) whales the presence of humpback...
