A gray whale named Varvara has broken records of all time by being that mammal with the “longest migration ever”. This 9-year-old mammal has created a record of swimming 13,987 miles from Russia to Mexico and came back to Russia in 172 days, which is less than 6 months of time.
The biologists were conducting a study on whale immigration for understanding the migration patterns of a rare population of gray whales more in depth and that is when they came across this achievement. The researchers had been tracking those gray whales that have a preference of swimming in the northwestern Pacific waters along the coast of Russia.
Varvara had set the records after the completion of the first half of her expedition, said the researchers at the Marine Mammal Institute of the Oregon State University when talking about the details of the trajectory and length of this grand journey.
Varvara’s trip from the Arctic waters of the north-west Pacific close to Sakhalin Island in Russia, the preferred feeding waters of the whale, to the breeding grounds off the coast of Cabo San Lucas, Mexico, has helped the mammal acquire the record for the longest transoceanic journey by about 2,000 miles. The return of her back to Russia had been the cherry on top.
According to the researchers, the most incredible and unique aspect of Varvara’s journey had not only been the recorded length that it has covered, rather the technique of her trekking in the open ocean.
In general, most whales are known to stick to the coast while swimming, therefore the scientists had the assumption that the grey whales belonging to the western Pacific region must be travelling in a loop from the Arctic Ocean to the South China Sea. On the contrary, Varvara had foregone the coastal landmarks and went across the Bering Sea without following any nautical reference points.
Varvara did not swim alone in the duration of her initial leg; she had been accompanied by Alex, a 13-year-old male whale, and Agent, 6-year-old female who had been by her side in this exciting episode.
