How would arthopods move?

Answer 1

Arthropod mobility depends on appendage adaptations for the type of habitat of the species; all of them have jointed legs of some type, used for walking or perching. Many have wings (e.g., class Insecta), and some have swimmeretes or limbs adapted for water movement (shrimp, krill, some crabs). In some crustaceans, walking legs (-peds) have combined functions as pincers (chela) called chelipeds.

Most insects have six legs, arachnids have eight, many crustaceans have ten; and in the case of myriapods like millipedes, they might have several hundred.
