The Flehmen Response is a particular type of curling the upper lip in ungulates, felids and many other mammals.



It is shown by many male mammals when they detect a scent and it facilitates the transfer of pheromones and other scents into the Jacobson's Organ.



The name "Flehmen" is from the German flehmen, which means to curl the upper lip.
