>>44481304>Down feathers, flight feathers, and display feathersAll feathers. All made of the same stuff. Yet slightly different in structure because they served different purposes

>Breast fat, body fat, fat between organs, blubberAll fat, all made of the same stuff, but are used in different ways. Animals lose/gain weight in different places at different ways. Men have more internal fat, that is, underneath the muscle, while women tend to have more fat above the muscle. Marine mammals will try to hold on to blubber because it's more important to keep the animal warm. Will they lose it if they are starved enough? Sure, but they lose it at slower rates.
