Mammalian Rhinarium Group
We study how mammals obtain sensory information from their rhinaria and what role this information plays in their lives. The rhinarium is the hairless, wet frontal part of the nose in many mammals. However, we also look at mammalian nose-tips in general. Rhinaria and nose-tips vary in shape, motility, color, skin structure, temperature, and moistness. A dog rhinarium is wet and cold, cows have wet and warm rhinaria, in a pig the nose-disc is dry and warm, and reindeer nose-tips are warm and furry.
Thermal images of mammalian noses, in the same order of species as above, but not necessarily of the same individuals.

Many people can relate to the popular pets and/or important working animals in our studies. The work is met by great interest and we are happy to reach out to a large audience of professionals, students and laymen.
