    Whales are sensitive to the sun’s damaging rays, leading them to adapt.

     

    New research reveals that whales get darker with sun exposure and even incur DNA damage from prolonged sun exposure as they age.  Blisters discovered on whales in Mexico prompted this research, which looked at blue, sperm, and fin whales after they returned from their migration to sunnier climes. One interesting find was darker sperm whales trigger a stress response that protects them from the sun since they spend more time near the ocean surface and receive more UV radiation.  They say this is a reminder that climate change is affecting every creature on the planet.
