In the Womb: Extreme Animals (2009)

This program selects several creatures from nature, explores their special ways of reproduction and pregnancy (gestation), and investigates how they mate, the changes of embryos from development to birth, and what happens after the birth of new life. The camera will go deep into the mother's womb and introduce in great detail the different stages of the development of individual animals' embryos, providing unusual and rare images for the audience. How can penguin embryos not be frozen? Why does the kangaroo embryo not fully develop, so it leaves the uterus and walks to the pouch by itself? Why is it life-threatening for many shark embryos to have siblings? What kind of animal reproduction made Darwin question the existence of God?
