Did you know that a hippo’s milk is a rose-colored pink? This is because a hippo secretes or releases two types of acids known as hipposudoric acid and norhipposudoric acid. These two acids tend to help keep hippos healthy. They are a natural form of sunscreen and moisturizer for their sensitive skin and they protect the hippo from harmful bacteria while in the water. This is why hippos can relax in some pretty toxic water with little health risk. WOW! pink, can you believe it? Keep following the OMG page kids, the facts are starting to get really good!
