Around halfway through a pregnancy, a fetus develops hair called lanugo all over their body. They shed most to all of it before they're full term. That hair is shed directly into the amniotic fluid, which is then ingested by the fetus, and (hopefully) stays in their intestines until birth or right after.

So, basically, fetuses eat their own hair, and since amniotic fluid is swallowed and excreted, you could say they're swimming in their own pee.

Fatal Familial Insomnia (nightmare fuel)

Chronic Wasting Disease.
