Biopsies of skin samples indicated evidence of DNA damage in the deepest layers of the whales' skin cells. Researchers concede that there is little hope of reducing these damaging affects within the next several years. They can only hope that whales' cellular repair mechanisms can adjust to offset this damage.鲸鱼皮肤样本的活组织检查显示出鲸鱼皮肤细胞最深层的DNA有损伤的迹象.研究人员承认想要在未来几年减少紫外线对鲸鱼皮肤损伤的希望很小.他们只能寄希望于鲸鱼的细胞修复机制能够调整以修复这些伤害. ________________________.Could whales adapt to this increased UV radiation by perhaps, getting "suntans"? These are the types of questions that will be taken into consideration in future studies.鲸鱼是否能通过皮肤变黑来抵御日渐强烈的紫外线呢?这些问题将会在未来的研究中得到重视.

Will skin damage in whales lead to skin cancer as it does in humans?
