Under arthropoda are 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 nauplius larval form; hexapoda named for their consolidated thorax with three pairs of legs.
Some text may show subphyla as "classes" but usually the term 'class' has a specific denotation within taxonomy; there are more than just three classes under these subphyla. Some examples would be class Arachnida, Chilopoda, Branchiopoda, Insecta, and Malacostraca - but there are many more.
Three classes of marine arthropods might be, Merostomata (horseshoe crabs),
Pycnogonida (sea spiders), and Branchiopoda (in the crustacean subphylum), but there are more than three classes which are marine.
Under arthropoda are 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.
This might depend on what is intended by "main" - perhaps by count or significance, by scope of habitat or global distribution, or by some other notional prominence; in taxonomy there are more than three arthropod 'groups' and one might pick any given three for varying reasons.
