Two humpback whales have made record-breaking crossings between Australia and Brazil. Scientists say the whales were identified by their distinctive tail markings and traveled about 9,000 miles. Humpbacks feed on krill and small fish in the warmer months and breed in tropical waters over winter. Researchers analyzed over 19,000 images taken in the past four decades and pinpointed two different whales at breeding sites in Australia and Brazil. Whales don’t typically travel between mating sites so it’s unclear why these two embarked on their journeys. The study was published Tuesday in the journal Royal Society Open Science.
