How do bugs walk with all those legs? This Demonstration provides a basic answer to that question for several terrestrial members of the phylum Arthropoda, namely insects, spiders, scorpions, centipedes, and millipedes. Each example is a simplified cartoon showing locomotive movement patterns (or gaits) of a terrestrial arthropod on a solid surface. These models are highly generalized. In reality, not every leg in a set moves at exactly the same time [2, 3]. Furthermore, some of these animals exhibit different or variable gaits with different movement speeds [3, 4, 10] or when burdened with extra weight [11]. Also, not all members of the example taxa behave exactly the same; there is always variation. See Details for a more complete discussion of the generalizations.
