Hello Hospital Supplies? Can I order a 15 litre tub of ultrasound jelly please?

I suppose it was inevitable that someone would apply the 4-D in-utero ultrasound scan to animals, but dammit it never occurred to me.

The results are some fantastic pictures, available from the National Geographic site, of animals in the womb, including this rather wonderful 18 inch elephant. More available in the, ahem, Daily Mail too.
