Animal Facts: Hippo Sweat

How are hippos able to stand out in the hot sun all day and never get a sunburn? Because their sweat is a natural sunblock!

Hippo sweat contains microscopic particles that scatter the light, so it's not concentrated on the hippos' skin. The sweat is also red in color due to orange and yellow pigments, which are able to aborb untraviolet light. While this red sweat helps keep the hippos from burning, it does tend to make it look like their bleeding - not a pretty sight!
