Male Lion Displays Flehmen Response While Near Drinking Lioness

In this footage captured in a grassy savanna, a lioness is seen drinking from a small pool of water. A male lion stands directly behind her, exhibiting the flehmen response—a behavior where an animal curls back its upper lip to expose the vomeronasal organ, or Jacobson's organ, located in the roof of the mouth. This action allows the lion to better detect and analyze pheromones and other chemical signals in the environment. The male lion repeatedly performs this facial expression while positioned near the lioness, who remains focused on drinking.
