On Saturday, just minutes after its twin came into the world in a more traditional manner, a Spanish baby was born in a completely intact amniotic sac — and it looks just as intense as it sounds.

In the video, you can clearly see the newborn and its still-attached umbilical cord, which is providing the baby with oxygen as it sits in its sac. You'll also notice it wriggling inside as the doctors look on.

Normally, this sac would be broken during the birthing process. When the fluid from the sac leaks out, we refer to it as a mother's "water breaking." In this instance, it's likely that the doctors had to cut open the sac with a scalpel to manually free the infant, just as Spanish physicians did when another baby was born in the amniotic sac earlier this year.

Although Spain has seen two of these extraordinary births in a year, it's actually an extremely rare phenomenon. In fact, only one in 80,000 babies is born in its amniotic sac, according to the Daily Mail.

This unusual birth is undoubtedly fascinating, and it likely provided a once-in-a-lifetime delivery experience for the doctors and nurses involved. With that said, the video is also not for those with a weak stomach, so be sure to take that into account before watching the Daily Mail's snippet of the footage below.

The video's original poster, who appears to be a nurse at the hospital at which the baby was delivered, wrote in another Facebook post that the video has now been watched more than 10 million times.
