Scientists report that two humpback whales make separate, record-breaking voyages across the ocean between Australia and Brazil. The reports describe the whales undertaking long-distance migrations and being identified during monitoring activities that track their movements. While the exact tracking methods and dates are not detailed in the provided excerpts, all outlets agree the crossings are notable for their distance and that they represent records for the route between the two countries. The coverage also describes the whales as humpback whales, a species known for extensive seasonal migration between feeding and breeding grounds. According to the accounts, the two whales complete the journeys independently rather than traveling together, with each crossing setting a new benchmark for the Australia–Brazil route. The reporting emphasizes the rarity of such confirmed long-distance crossings and frames the sightings as valuable for understanding whale migration patterns and how animals navigate ocean distances. Overall, the information comes from scientists who observe and document the whales’ movements and conclude the crossings are record-setting.
