                                The hooded seal produces the world's most fatty milk, with a staggering fat content of over 60%, essential for its pups to survive in the frigid Arctic waters. While cow's milk is a common reference point, the reality is that fat percentages vary dramatically across different species and even among domesticated animals. This variation is tied directly to the offspring's nutritional needs and the environmental conditions they face.
