What animals protect themselves from the sun?
Some fish, birds, amphibians, and reptiles have the genes to produce gadusol, a chemical that can act as a sunscreen. Hippopotamuses produce “sweat” made of reddish pigments that protect them from infections and sun damage.

Animals with very little hair such as pigs and their relatives, hippopotamuses and warthogs, are particularly at risk and they often coat themselves with mud to act as a sunscreen. They have some very interesting adaptations to sun protection.
Do animals get sun tans?
So, do animals ever get sunburned? Yes. “Marine mammals, and specifically cetaceans [whales, dolphins and porpoises], are an exception because they don’t have fur; they don’t have scales,” said Acevedo-Whitehouse, who has been studying sunburn in whales for over five years.
What animals can get a tan?
Wild animals with feathers and thick fur are those animals defenses. Dolphins and whales also become sunburned if exposed to the sun too long. Short haired dogs, cats, and other pets get sunburned as well.
Can dogs tan in the sun?

Do cows feel the cold like humans?
Winter weather may be tough on people, but cows are well adapted to the cold and, because of their higher body temperature, actual prefer things to be cool.
How cold is too cold for a cow?
Cold stress in cattle is when their body temperature drops because their body’s natural metabolic processes plus the heat provided by a heavy winter coat are not enough to keep them warm. If a cow has a dry, heavy winter coat, she can withstand temperatures below 18ºF before feeling any cold stress.
