Millipedes have the most legs of any animal. The distinctive traveling wave in its walk is a kind of auto-pilot. Using innovative slow-motion macro video, we observe the traveling wave motion of the legs move from the back to the front of the animal's long body. The workings of the walk involve a specific network of neurons called central pattern generators (CPGs) that produce a sequence of automatic muscle movements. This rhythm repeating over time is called a metachronal rhythm. Most arthropods walk this way, but the millipede's plenitude of legs makes the pattern clearly visible.
