* Some [[Reproductive_Behaviour_-_Attractivity_Behaviour_-_Anatomy_%26_Physiology#Pheramones|pheramones]] are less volatile and need to be detected by the '''vomeronasal organ'''.
* Some [[Reproductive_Behaviour_-_Attractivity_Behaviour_-_Anatomy_%26_Physiology#Pheramones|pheromones]] are less volatile and need to be detected by the '''vomeronasal organ'''.

* Male closely approaches the source of [[Reproductive_Behaviour_-_Attractivity_Behaviour_-_Anatomy_%26_Physiology#Pheramones|pheramones]] and will nuzzle the female genital region.

* Flehmen behaviour is characterized by:
* Flehmen behaviour is characterized by:

** Curling of the upper [[Lips_-_Anatomy_%26_Physiology|lip]].
** Curling of the upper [[Lips_-_Anatomy_%26_Physiology|lip]].
* Curling of the upper [[Lips_-_Anatomy_%26_Physiology|lip]] closes the '''nostrils''' and allows negative pressure to form in the '''nasopalatine duct'''.
* Curling of the upper [[Lips_-_Anatomy_%26_Physiology|lip]] closes the '''nostrils''' and allows negative pressure to form in the '''nasopalatine duct'''.
* Flehmen behaviour allows less volatile pheramones to be examined by sensory neurons in the '''vomeronasal organ'''.
* Flehmen behaviour allows less volatile pheromones to be examined by sensory neurons in the '''vomeronasal organ'''.
