NEW YORK — Scientists have spotted two humpback whales that made separate, record-breaking crossings between Australia and Brazil.

The whales were identified by their distinctive tail markings at the two locations about 9,000 miles apart. They traveled in opposite directions and journeyed farther than any humpback known so far.

“It’s a very rare event, but it is a really wonderful demonstration of just how wide-ranging these animals are,” said Phillip Clapham, former head of a NOAA whale research program who was not involved with the new findings.

Humpback whales are known for roaming long distances across major oceans in predictable patterns, typically following migration routes learned from their mothers. They feed on krill and small fish in the warmer months and breed in tropical waters over winter.
