Many have heard that hippos produce pink milk. It's one of the most viral zoological myths! But in fact, this is just a misconception. Hippopotamus milk is normal, white, like that of all mammals. But how did this astonishing legend come about? The myth of pink milk originates from a unique feature of hippopotamus skin. These animals secrete a reddish-orange oily fluid, often called "bloody sweat." It contains two special pigments: hipposudoric and norhipposudoric acids. These powerful acids perform dual functions. They act as a natural sunscreen, protecting the hippos' sensitive skin from the scorching African sun and UV rays. They also have antiseptic properties, preventing bacterial growth and promoting the healing of minor wounds. Thus, although "bloody sweat" has a pink or reddish tint, it is completely unrelated to milk. Hippopotamus calves, born weighing up to 50 kilograms, drink their mother's regular white milk, rich in fats and proteins for their rapid growth. So, hippos' pink milk is just a myth. But the fact that they have natural pink "sunscreen" is a true miracle of nature, demonstrating incredible adaptations. Nature always holds amazing secrets, waiting for us to discover them!
