The secretion of this reddish sticky fluidfrom a special gland in the Hippo skins is often referred to as “bloodsweat” However, it might be shocking news for you if we say that this fluid is not really “sweat”. The primary role ofsweatin mammals (including humans) is to regulate body temperature. On the other hand, this secreted fluid of the Hip...See full list on animaliafacts.comWhen hippos secrete their unique fluid, exposure to sunlight and oxygen causes it to turn areddish color.
This reaction led early European explorers in Africa to mistakenly call it “blood sweat,” as it looked eerily similar to blood. So, what’s the science behind this phenomenon?
