In the Womb: Animals is a two-hour documentary which will be broadcast on the National Geographic Channel on December 10th, and on UK’s Channel 4
over the Christmas holidays on Thursday, 21st December.
Produced by Pioneer Productions, it features, for the first time, the use of state-of-the-art four-dimensional ultrasound technology to observe the embryonic and foetal development of mammals. The intra-uterine footage in the film has been generated using a combination of ultrasound and computer-generated imagery.
The film focuses on dogs, dolphins, and elephants, charting the development of the latter from the single-cell stage through to its birth. The elephant has a gestation period of 22 months, the longest in the animal kingdom.
There’s an extended sneak preview of the film at the National Geographic Channel website, and here’s a clip from an earlier film by the same production company, about a more familiar mammalian species:
