Recent video of an ultrasound shows a pair of twin girls punching each other while in utero.
The video, taken at a hospital in China, shows the two girls facing each other, and one ultimately punches the other. Her sister then punches back.
The twin’s father told the Daily Mirror, “When we saw this video, it was a big surprise to us.”
The video was taken in December and the girls, nicknamed Cherry and Stawberry, were born last week.
The head of the prenatal center at the hospital said, “It can be dangerous because it is like the twins are growing in the same ‘room’ when normally twins develop in two ‘rooms.’ It happens once in every 30 million cases.”
