Using high-quality MRI technology, doctors were able to see two twins fighting for space inside the womb.
In a video that has gone viral, the MRI footage shows one of the twins kicking the other in a possible effort to get more space.
Watch the video below.
The Huffington Post reports that this type of imaging is used to study how twins can take blood away from one another and to get a closer look at fetuses, according to a London doctor.
This imaging also offers clearer images of fetuses who reportedly stretch, hiccup, yawn and open their mouths.
There is a lot of debate on how much fetuses can do while inside the womb and what constitutes as movement or early brain maturation, according to The Huffington Post.
The video has gotten a lot of attention, humorously showing the world that maybe twins do start fighting even before birth.
