Knows nose

The image above is a composite of infrared photos of the noses of a number of mammals (Row 1: Dog, horse, sheep, pig, cat, goat; Row 2: Rhesus monkey, rat, kinkajou, rabbit, cow, degu; Row 3: Zebu, ring-tailed lemur, meerkat, harbor seal, moose, raccoon dog; Row 4: Polecat, arctic fox, lynx, raccoon, common eland, human). The photographs were taken by zoologists at the University of Lund in Sweden and the temperatures of the noses range from 68°F (20°C) to more than 100°F (38°C). Led by Ronald Kröger, who previously researched animal vision, they are studying the wet and hairless nose tips of creatures other than humans – specifically a structure called the rhinarium and why it helps to keep it cool. The scientists have not yet published any of their findings, but look for papers soon from the newly established nose research group.
