Whales migrate from polar regions to fill body damage

Changing the temperature also changes the speed of blood flow in the whale’s body and the skin cells also begin to form again.

According to a study, whales living in polar waters migrate to lower latitudes for food and to keep their skin healthy, because prolonged living in the polar regions affects their health. Food is also not easily available. Researchers say that with the help of this study better measures can be taken to conserve marine organisms.

The speed of blood flow also changes
According to a study published in a journal called Marine Mammal Science, ‘killer whales’ living in protected areas of Antarctica begin to migrate to lower latitudes in search of food. Changing the temperature also changes the speed of blood flow in their body and skin cells also start to form again. This cures the malfunctions in the outer layer of their body.

Robert Pittman, lead author of this study from Oregon State University in the US, said, ‘I think whales don’t change their skin, but it is an important physical requirement of every organism. Scientists say that all birds and mammals regularly clean their skin, fur or feathers. Migrating to warm water helps whales to revive their skin metabolism. This makes them suitable to live in every kind of environment and their body heat also remains.

Study done like this
For this study conducted for eight years, the researchers had placed 62 satellite tags on the killer whales. During this time he found that whales living in the waters of Antarctica migrated to other areas in a circumference of 11 thousand kilometers. He said that during this period most of the whales migrated rapidly and stopped massively.

Gives birth to children even in cold areas
Researchers have also taken photographs of newborn killer whales in Antarctica, indicating that they do not need to go into hot water to give birth to whales. He said earlier it was estimated that large whales go to the tropics to give birth to their babies. But the new study reveals a different picture of whales.
