How does a hippo make its own sunscreen?
On a sweltering day, when most people are cooling off at the pool or lying motionless under a high-powered fan, Dr. Brady Barr found himself decked out in a 196-pound (89-kilogram) armored suit smeared with mud and dung. In the name of scientific discovery, the scientist was on a mission to collect a wild hippo’s sweat before it dried. You’re probably wondering why anyone in their right mind would risk their life by approaching one of the most aggressive and dangerous animals in all of Africa. Considering that hippos cause more deaths than any other animal on the continent, it’s a reasonable question [source: Harlow]
