Happywhale tail-recognition software shows animal crossed oceans for an extraordinary migration In a whale of a tale about whales’ tails, a team of marine ecologists has tracked a humpback whale (Megaptera novaeangliae) more than 13,000 kilometers, from Colombia to Tanzania. The observation was made possible by modified facial recognition software designed to identify the giant aquatic mammals by the distinctive shapes of their tales, or flukes. It beats the previous of record for a humpback of 10,000 kilometers. Such a long migration “is extraordinary,” says Jeremy Goldbogen, a comparative physiologist at Stanford University who was not involved with the work, published recently in Royal Society Open Science. The observation also demonstrates the utility of the fluke-identification...

Famous for its beaches and vibrant parties in the Southern Hemisphere’s summer, Rio de Janeiro now has an attraction for winter: humpback whales. The tourism agency of Niteroi, Rio’s sister city across the Guanabara Bay, on Thursday launched a whale-watching program that enables tourists to closely observe the mammoth mammals.

Most concentrate in the Abrolhos region, an area of coral reefs off the coast of Bahia and Espirito Santo states know...

A humpback whale, likely lured by a trawling net capturing masses of Antarctic krill, became entangled last month and died in the Southern Ocean. Three dead juveniles were caught in the same company's krill nets last year. Scientists say the humpbacks may have been malnourished while forced to compete for food with a burgeoning industry harvesting the tiny crustaceans - the linchpin in the Antarctic food web - for use in pharmaceuticals and fish feed. The fishing company, Norway's Aker BioMarine, said these were its first cases of whale bycatch in 15 years of harvesting krill in Antarctica, and that it has since reinforced its ships' devices for keeping marine mammals out of its nets. Pål Skogrand, director of Antarctic affairs and sustainability at Aker BioMarine, said the c...
