Tiny animal kingdom: the elephant foetus at 12 months, when it is 18 inches long and weighs approximately 26 lbs. It can use its trunk, and can curl it right up into its mouth and over its head.
An unborn elephant, tiny but perfect in every way. A dolphin swimming in the womb, just as it will have to swim in the ocean the moment it is born. An unborn dog panting.
Using an array of technology, the images reveal what until now has been a secret – exactly how animals develop in the womb. They were created by the same team who in 2004 showed how human embryos "walk in the womb".
Using a combination of three-dimensional ultrasound scans, computer graphics and tiny cameras, the team were able to show the entire process from conception to birth.
"These kind of images from inside animals have never been seen before," said Jeremy Dear of Pioneer Productions, who made the film.
