#1 Fetus in fetu is characterized by an abnormal mass in the body that resembles a fetus.

Only one in 500,000 people has to deal with this condition.

#2 Most of these fetuses are effectively dead, but sometimes, they can receive blood from the host.

But even those that are connected to a constant blood supply often have severe developmental issues, since many of them lack brains.

#3 In 2003, a seven-year-old boy named Alamjan Nematilaev discovered that he had a fetal twin living inside of him.

The tiny being, which was far more developed than most, even looked like its host brother.

#4 One theory for how fetus in fetu works has to do with the development of identical twins.

Since these twins share a placenta, it is possible that weaker twins attach themselves to the stronger ones and live off of them, much like parasites.

Can you imagine finding out that you had a twin living inside of you that was using your body as a host? It's a trippy thought that illustrates just how weird human biology can be.
