                                The chemical makeup of milk varies considerably from one species to another, with a hooded seal's milk being over 60% fat while a rhino's is less than 0.2%. What is found in the milk of mammals, regardless of species, is a complex and dynamic fluid containing proteins, fats, sugars, vitamins, and minerals designed to provide complete nourishment and immune protection to their young.
