So, it is our first scar. 2.During the research “A Jungle in There” that took place in a 2012, scientists investigated the biological diversity in belly buttons of 60 people. They identified a total of 2,368 different species living in belly buttons! While the average person had 67 species swarming around in there. 3.Many mammals have no belly button at all. Most of them as well as certain humans have their navels obscured by fur, fade over time, or have a thin scar or small bump instead. 4.Belly button piercing takes from six months to a year to heal.

They used a specific method of “navel contemplation” called Hesychasm, believing it gives a broader insight into divine glory. 6.“Omphaloskepsis” is the scientific term for navel-gazing. 7.Earth has a belly button as well! A giant pothole colloquially named “Cosmic Navel” is situated in the heart of Utah’s Grand Staircase-Escalante National Monument. This unique landform is almost 200 feet wide, and geologists believe it may be up to 216,000 years old.
