New research revealed some more human signs at whales: as it appeared they sunbathe to be protected from destroying influence of UF-beams, as well as people. Research began when scientists in the Gulf of Mexico began to notice suntanned whales. It was revealed that influences of UF-beams (radiation) on sea flora and fauna amplified as a result of ozone decomposition.

Using samples of mitochondrial DNA, researchers studied fins of cachalots to find out, what genetic ultra-violet influences are observed on their skin. They found out that whales with big level of melanin in skin were better protected from defeats of skin and DNA damages, the same as black people are less inclined to damages by the sun. Remains to unknown, whether ultraviolet influence promotes increase of vulnerability of whales to melanoma development. At suntanned whales DNA changes are observed, similar changes also were noted at people that certainly is connected with aging. Research shows that interactions of systems which we can study in researches in public, have consequences for fight against aging of skin and cancer development, scientists reported.
