HOw DoesThe(Inside)Pregnant Womb of a Mammal or a Bird’s Egg Looks Like?

Captured using revolutionary four-dimensional imaging technology and anatomically accurate models, scientists have managed to shed light on the world of mammals inside the womb.

As diverse a bunch as they are - elephant, dog, dolphin and penguin are all shown united by their similar stages of development.

Say cheese: A baby dolphin seems to be smiling for the camera as he prepares for his big splash

Scientists captured the images for a National Geographic Documentary called 'Animals in the Womb'. 

The images were also used on a Channel 4 documentary 'Animals in the Womb' which aired in 2009. 

The documentary explores the marked similarities between very different animals. 

Sleepy?: A dog foetus could be mistaken for a rat in these ground breaking images. The animals - as diverse as they are - strike remarkably similar poses in the womb
