Researchers at National Geographic have done something incredible: they were able to take photos showing different animals growing in their mother’s womb. To do this, they used small cameras connected via a 4D-Ultra sound scanning system. The result is some truly stunning images. We can now see how the animals actually looked a few weeks before they were born. Here are some of the best pictures in this series. They are truly an absolute miracle!
