In a wiggly clip from the series Micro-Monsters, host Sir David Attenborough quietly marveled over the magnificent physiology of how a millipede moves, noting that the species have remained the same for millions of years.
Millipedes were among the first arthropods to move up out of the water onto the land. They can have up to 750 legs, grow to lengths of 30 centimeters, and live for as long as seven years. This body plan is so efficient that it has remained largely unchanged for hundreds of millions of years.
