How do emu's move?

Emus walk and run on two legs. As an emu walks forward, its long neck has a slight tendency to bob a bit, and its head moves accordingly as it curiously checks out anything of interest to it.

Emus possess the unique ability to make sudden sharp turns. When running at top speed, the physiological structure of their feet enables them to make sudden 180-degree turns which not even a smaller, lithe creature can do.
