And... I did read somewhere that the skin of a tiger is also striped... not only the fur??,,,,,Ludwig Venter said:
I found out the other day, thanks to QI, that kingfishers aren't blue
They just look blue because of the way their feathers refract light (some butterflies wings do this too).Their feathers are actually pigmented brown!
Similarly, polar bears are not white. Their outer fur has no pigmentation at all, however it reflects light across the spectrum, and thus appears white.
Having just Wiki'ed it, you are quite correct. (That's assuming you believe Wikipedia)
