Why Don’t Animals Need Sunscreen?

The video explores how different animals protect themselves from the sun. While humans use sunscreen, animals like birds, bears, and reptiles have natural coverings like feathers, fur, or scales. Some animals, such as pigs and elephants, use mud as a protective layer. Others, like alligators and fish, produce a chemical called gadusol for sun protection. Humans don't produce gadusol, possibly due to nocturnal habits in the past. Scientists are studying gadusol for potential sunscreen use. Whales, lacking natural protection, have unique healing methods for sunburns.
