The shore saw a gray whale (Eschrichtius robustus) of Namibia between May and July of 2013. This incident was strange as these species were rarely spotted in the Atlantic Ocean. They are usually found in the northern hemisphere. A report depicts that these animals have travelled a minimum of 20,000 kilometres that is approximately 12,427.4 miles. In short, they have travelled halfway around the planet while setting a new record for migration among mammals, except for humans.
Rus Hoelzel and his colleagues in the UK at Durham University used the tissue samples obtained from the whale’s skin and examined the DNA of the whale to find its origin. Comparing the analysis report with the other populations of whales, it was found that this whale was a male. It seemingly was born to the jeopardized western population of the North Pacific and was located along the shore of eastern Asia. This implies that this whale has travelled a minimum of 20,000 kilometres to reach the southern Atlantic, and the circumference of the earth is a little more than 40,000 kilometres. Hoelzel says, “This is the record really for an in-water migration if you’re assuming that this individual started its life in the northwest Pacific, and it found its way to Namibia. That’s as far as any vertebrate has ever gone in the water, as far as we know.” The landdwelling mammals come considerably in action. A grey wolf makes a record of roaming for more than 7000 kilometres in just one year.
According to the statement of Oregon State University, the whale naming Varvara moved approximately 22,500 kilometres that are around 14,000 miles. The scientists of the University assisted in managing a study related to whaletracking. Varvara (Russian of Barbara) moved away from her initial feeding territory, Russia’s Sakhalin Island. It swam across the Pacific Ocean to the West Coast of the US to Baja, Mexico. The journey of Varvara exceeded the records listed on the Guinness Worlds Records website. The previous history was made by a humpback whale, which swam around 10,190 miles round between the warm breeding waters around the equator and the Arctic and Antarctic regions in the colder food-rich water. These records are helpful, but the lead author of the research, Bruce Mate, thinks that these long journeys say a lot more about the whale and not only their strength to swim.
Varvara hit the three major breeding regions for eastern gray whales during her journey of 14,000 miles. Bruce Mate, also a director at Oregon State University of the Marine Mammal Institute, was surprised by this journey of Varvara. Mate said that it is a much powerful proof that going to Mexico might mean that she is from Mexico. It was believed that Varvara was an endangered western whale, but now looking at the ability and the possibility of the whales to navigate in the open water over such a vast distance is exciting. That might mean that some of the western grays are eastern grays in real. It was believed that only about 150 western gray whales are existing, but now these numbers might be lesser. Mate said that the studies in the past show the genetic difference designated between the species, but it is now recommended to take a closer look at it.
A researcher team of Sea Search Research and Durham University and Conversation NPC discovered a gray whale spotted at the shore of Namibia had travelled the earth around halfway to reach there. This whale is the only gray whale that swam the longest distance while migrating for more than 16,700 miles and setting the species’ record. And migrating is not only an exceptional characteristic thing about this mammal. There is more to see!
Distance record in water-migration
A male gray whale, approximately 40 feet long, has made a record. A research paper was published in the Royal society’s biology letters. According to that, the scientists of Conservation NPC and Sea Search Research and Durham University discovered a huge gray whale at the shore of Namibia. It is believed that the whale travelled about halfway around the earth. This species belongs to the northern Pacific region. Some fishermen found this one initially in Walvis Bay in 2003. The scientists and oceanographers noticed the incident, and that made the beginning of the study. First and foremost, it was the first time that they remarked it so far away from home.
Study shows the gray whales are rare to come into sight.
A scientists’ team got a tissue sample of the whale. Simon H and Tess Gridley picked up the additional examination from the Conservation NPC and Sea Search Research and teamed up with an evolutionary biologist, Fatih Sarigol, and A. Rus Hoelzel, a biologist of Durham University. The entire group completed a DNA analysis of the genes of the gray whale. Furthermore, they matched it with some other samples stored in the US’s National Center for Biotechnology Information. The research gave the surprising revelation that the gray whale spotted at the Namibian coast was related directly to the endangered western gray whales in the Northern Pacific Ocean. A study shows that only 200 western gray whales are left around the world.
