Sticking their necks out for scientific research.

These giraffes at a zoo near London are helping researchers find out just how their spindly legs work.

Experts are using special technology to measure the animals' leg movements. They want to see if being tall is a help or a hindrance to moving around.

The scientists also hope to solve the evolutionary mystery of how these animals developed from their more modestly proportioned ancestors.
