This is one of the most widespread divisions of the animal kingdom, certainly the largest. Arthropod means jointed legs but whereas vertebrates have only four legs, some of these invertebrates have many more. The main classes of arthropods are insects, arachnids(spiders, scorpions and mites), millipedes and centipedes, and crustaceans(crabs, lobsters and shrimps)
