What are the 6 classes of phylum arthropods?

Answer 1

Note that in some texts the subphyla may be referred to as classes; occasionally the taxonomic discipline appears somewhat fluid.

Arthropoda has subphyla Chelicerata, Myriapoda, Crustacea, and Hexapoda. (There is also an extinct class Marrellomorpha and an the extinct Trilobite subphylum). The chelicerata, like Spiders, scorpions, mites, etc., get their name from having appendages appear before the mouth; myriapods like centipedes and millipedes characterized by a high count of body segments and legs; crustaceans like crabs, shrimp, woodlice characterized by their biramous (two-part) limbs and a specialized larval form; hexapoda named for their consolidated thorax with only three pairs of legs.

Classes below phylum Arthropoda could be selected from these subphyla; for example classes Arachnida, Chilopoda, Branchiopod, Insecta, and Malacostraca - but there are many more classes.

Answer 2

The five major classes of arthropods are as follows with one example each:

1. Arachnida; Ex. spiders

2. Crustacea; Ex. crabs

3. Diplopoda; Ex. millipedes

4. Chilopoda; Ex. centapedes

5. Insecta or Hexopoda (insects)
