Belly buttons harbor unique bacteria that form a "fingerprint."

[missyrain]

This fact is so interesting and a bit gross! Each person's belly button has a unique microbial ecosystem. I remember reading about a study where scientists discovered hundreds of bacteria species in belly buttons. Have you ever wondered what your belly button fingerprint looks like?

Right? It’s wild how unique our belly buttons are! I never thought about them having their own little ecosystem until I read that too. It's kind of fascinating and a bit gross at the same time! I wonder what kinds of bacteria are hanging out in mine!
