  • A particular type of curling of the upper lip in ungulates, felids, and many other mammals, which facilitates the transfer of pheromones and other scents into the vomeronasal organ, also called the Jacobson's Organ. In the flehmen reaction, animals draw back their lips in a manner that makes them appear to be "grimacing". The action, which is adopted when examining scents left by other animals of the same species or prey, helps expose the vomeronasal organ and draws scent molecules back toward it. This behavior allows animals to detect scents, for example from urine, of other members of their species or clues to the presence of prey. Also called flehmen response or flehmening.
