Joint-Legs (Arthropoda)

Joint-Legs (Arthropoda)

If your animal has jointed legs and no spine, you can find it in the Arthropoda phylum. This includes most, if not all, of the animals we commonly call "bugs' as well as the crustaceans. Scientists have described 500,000 species of arthropods and believe that up to to 10,000.000 species are alive today.

The classes of this phylum include the six legged insects (Insecta), the eight legged Arachnids (Arachnida) including spiders , scorpions and ticks the hard bodied Crustaceans (Crustacea) including crabs, shrimp and barnacies and Malacostraca which includes the sowbug or pillbug.

Other Arthropod classes are Merostomata-home of the Horseshoe crab, Millipedes (Diplopoda) and Centipedes (Chilopoda)
