Humpback Whale Sets Record with 15,100 km Ocean Crossing Between Australia and Brazil

A new study published in Royal Society Open Science documented two record-breaking humpback whale journeys between eastern Australia and Brazil, with one whale covering more than 15,100 kilometers, the longest distance ever confirmed between two sightings of the same individual whale. The research, led by Griffith University scientists, analyzed 19,283 fluke photographs collected over 40 years. The findings strongly support the Southern Ocean Exchange hypothesis, suggesting that whales from distinct breeding populations occasionally meet in Antarctic waters and then migrate home with a different group.
