Fun Facts The unusual facial grimace depicted here is an example of flehmen, a German word, that describes the action of an animal analyzing a scent signal in this way. Practiced by most hoofed animals and many carnivores. This action causes ducts to open in the mouth and nasal passage, allowing scent signals to be transferred and analysed by a special organ called the vomero-nasal organ or (Jacobson's organ in reptiles). #big5 #buffalo #safari #instanimals #wildlifephotography #facts #wildlife #naturephotography #nature #thisisafrica #underafricanskies #fieldguide #bushlife #tour #toursouthafrica https://www.instagram.com/p/BoHO2BnhOFM/?igshid=dceywmxu0ptd
