A whale has set a world record by covering a distance of 20,000 km from the place of its birth. Except humans, no mammal on earth has been able to migrate such a distance. Earlier this record was held by a gray wolf who traveled 7000 km.
The gray whale seen in 2013 off the coast of the African country of Namibia has set a world record for migration. This earth’s largest mammal had traveled about 20000 kilometers to reach this country of the continent of Africa. Actually, it was quite strange to see this creature at one end of the African continent. Gray whales are rarely seen in the North Atlantic Ocean of the Northern Hemisphere. The coming of this creature so far is a puzzle for scientists.
This whale is found in the cold waters of the Atlantic
The scientific name of the gray whale is Escricheus robustus. It is found in the cold waters of the North Atlantic Ocean. It turns out that this gray whale traveled 20000 km to reach Namibia. This distance is almost impossible to cover for any mammal except humans. After which many scientists also did research about the migration of this organism.
Claimed to be born in the North Pacific
Russ Holzel and colleagues at the University of Durham in the UK analyzed the DNA from tissue samples from whale skin to trace its origin. Comparing it with another gray whale, they found it to be a male gray whale. Scientists speculate that it probably originated in an endangered western North Pacific population found off the coast of East Asia.
World record set by swimming 20000 km
Scientists claim that this means that it traveled at least 20,000 kilometers to reach the South Atlantic. The circumference of the Earth is a little over 40,000 km. This means that this creature has traveled the same distance as half the world to reach Namibia.
This record was previously worked by Gray Wolf
Russ Holzel said that this is actually the world record for migration in water. If you believe that this whale started its life in the North-West Pacific and it reached the shores of Namibia, then it is a big deal. As far as we know, no mammal other than humans has covered such a long distance. Earlier, a gray wolf living on land had covered a distance of about 7000 km for migration.
