Event overview
Two humpback whales set records swimming between Australia and Brazil
Two humpback whales were recorded making separate crossings between Australia and Brazil, with each traveling about 9,000 miles and identified by distinctive tail markings at eastern Australia and Brazil. Researchers analyzed over 19,000 whale images from four decades to identify the individuals, but the routes taken were not definitively established. The findings appeared in Royal Society Open Science (per New York Post) and were echoed by ABC News and the Washington Times, which report opposite-direction crossings and confirm the 9,000-mile span, though some specifics vary by article. Disagreement centers on whether exact routes were traced and the directions of travel beyond the broad east–west crossings, with ABC and NY Post providing corroborating distance data.
