Whales-patriots train their offspring to migrate over the ocean
The researchers have gathered and examined the material from 1647 species of white whales from 45 spots all over the Pacific seashore at Chukotka, Kamchatka, and Alaska. The scientists have utilized data from satellites to track the movements of animals, as well as DNA analysis to establish the relationship between species.
It has been turned out that the white whales from the Northern part of Pacific Ocean are geographically divided into three groups which do not crossbreed. Notably, white whales migrate over the same routes in many years.
The researchers note that adult species train their descendants to keep migration traditions of ancestors: parents intentionally travel in the proximity of their calves and show the route several times.
