About White color in Nature

What is the common theme between snow, splashing water, clouds, polar bear fur, white weasels (ermines), whipped egg whites, and the foam on a beer head?

The first lesson highlights multiple entities that appear pure white within our natural surroundings. And the unifying concept behind the white color.
Most of the objects that are pure white in nature are due to masses of air bubbles that are held in place by a transparent netting. This allows light to be bounced around by the chaotic reflective surfaces.
Bouncing light waves off air/gas molecules is a primary reason that objects are white in nature. However, there are others.
If mynah bird feathers are white because of disorganized air molecules within the shafts of the feathers, what about other creatures?Is there a common theme to having whiteness in living creatures?
