Supernumerary nipple
A supernumerary nipple (also known as a third nipple, accessory nipple or polythelia) is an additional underdeveloped nipple occuring in mammals including humans. Often mistaken for moles, supernumerary nipples are diagnosed at a rate of 2% in females, less in males. The nipples appear along the two vertical "milk lines" which start in the armpit on each side, run down through the typical nipples and end at the groin.
In Popular Culture
Actor and singer Mark Wahlberg is commonly thought to have such a nipple below his left breast.

- The assassin Francisco Scaramanga from the book and movie The Man with the Golden Gun
- Eccentrica Gallumbits from the book and BBC series The Hitchhiker's Guide to the Galaxy
- Krusty the Clown from The Simpsons television show
