How many legs do arthropods have?

It varies. Typically insects (which are arthropods) have 6, although it can vary depending on species. Because the name "arthropod" refers to any organisms with exoskeletons, there is no exact number of legs that an arthropod may possess. Insects in general possess 6 limbs, while arachnids such as Spiders have 8. Crustaceans like lobsters or crabs may support 10 or more. Still, some species in the subphylum myriapoda such as millipedes or centipedes may contain at least 9 pairs of legs. The leggiest specie of arthropod, Illacme plenipes, which is a Californian millipede, has been recorded for having 750 legs.
