LEG-POWER: FINDING GROUND LIKE THE CENTIPEDE & MILLIPEDE

TRAINS or trailers of the animal kingdom, centipedes and millipedes, both belonging to the class Myriapoda, are arthropods with fascinating mechanisms.

Despite their similar segmented bodies and numerous legs, these two creatures exhibit distinct styles of movement, driven by their dif fering anatomies and evolutionary adaptations. Understanding how centipedes and millipedes move provides insight into the complexities of their behaviour, ecology, and evolutionary history.

A 'hundred' legs

With their flat bodies and typically fewer legs (ranging from 15 to 191 pairs), centipedes are fast, agile predators. Their locomotion is characterised by a smooth, sinuous, and coordinated movement, which allows them to navigate quickly through their environments, usually in search of prey. Centipedes have one pair of legs per body segment, and their movement is primarily powered by alternating waves of leg movements.

The key to centipede locomotion is the coordination of their legs. When a centipede moves, the legs on one side of the body move in a synchronised fashion, followed by the legs on the opposite side. This creates a wave-like movement that propels the centipede forward. The legs move in a complex, sinusoidal pattern that provides stability and speed.
