Shave a Tiger and It Would Still Have Stripes Underneath

If you ever find yourself wondering whether a tiger's iconic black stripes are just a fur thing, congratulations — you have an unusual but excellent question. The answer is no. Tiger stripes extend all the way down to the skin. Shave a tiger (please don't) and you would still be looking at a fully striped animal. The pattern is baked in.

This is because the pigmentation — melanin, the same stuff responsible for human freckles and tans — is deposited in the skin's surface layer, not just in the hair follicles. The hair grows out of pigmented skin, so the stripes appear on both. It is essentially the same mechanism that gives some animals spotted or dappled skin under their coats.

No two tigers have the same stripe pattern, much like human fingerprints. Researchers can actually identify individual tigers in the wild by photographing their stripes — which is a significantly safer method than, say, checking their ears for a tag. The uniqueness of each pattern is thought to help tigers recognize each other, though they are mostly solitary animals, so these reunions are rare.

What makes the tiger stripe doubly strange is that they serve as camouflage in tall grass and dappled forest light — the bold black and orange that seems so obvious in a zoo is surprisingly effective in the wild. The stripes break up the tiger's outline so well that prey animals often don't notice the predator until it is far too late to reassess their opinion of tall grass.
