Researchers at National Geographic have managed to do something unbelievable: they succeeded in taking photographs showing various animals growing inside their mother’s wombs. In order to do this, they used small cameras that are connected through a system of 4D-ultrasound scans. The result is some truly breathtaking images. Now we can see what animals really look like a few weeks before they are born.
Here are some of the best pictures from this series. They really are an absolute miracle!
