Scientific research into a herd of Arctic reindeer is showing evidence of the possibility of the animals actually having red noses, and not just from drinking too much eggnog. Researchers in the Netherlands and from the University of Rochester in New York examined and compared the noses of a couple of reindeer with those of five human volunteers with surprising results.
It turns out that the snouts of reindeer have an extra dense network of capillaries in them, about 25% denser than those of humans. The red blood cells being carried by these capillaries give a red hue to the reindeer noses. Some might even call it a glow - especially during thermographic imaging after a good stiff trot on the treadmill.
