Interesting facts about #hippos:

• it doesn't have true #sweat glands, and the secretion they secrete is what people call "blood sweat"

• despite it's name, this #secretion is neither #blood nor sweat. Instead, it's a blend of #hipposudoric #acid and #norhipposudoric acid (#protects against #bacteria)

• milk is white like all mammals, but their skin secretes a secretion that turns the milk pink

• it can even nurse underwater if it wishes
