The first remarkable close-up pictures of animals in the womb

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.

Researchers used scans to track elephant calves developing for almost two years in the womb - the longest gestation period of all mammals.

It shows at 16 weeks the elephant foetus starting to look more like an elephant as the trunk develops.



At almost a year, the trunk is longer than the legs, and by 14 months, the characteristic elephant ears are visible. They will eventually grow to almost two feet across to help regulate the body temperature of the fullymature-elephant. At birth, he will weigh nearly 260lb and be able to take his first steps in minutes.

There are galleries of photos here, here and here.
