I don't think polar bear fur is exactly transparent
So there has been this story going around that polar bear hair strands are transparent tubes.
They might be tubes, but I don't think the walls of a polar bear hair strand are necessarily transparent.
From what I've seen in the microscopic pictures, the walls of a polar bear fur strand look either translucent or opaque.
Is it ok to disagree with the thought of polar bear fur being transparent, or does disagreeing with this thought make me a bimbo?
