What are the 4 main classes of arthropods?

What are the 5 classes in the phylum Arthropoda?

There are 5 major classes of arthropods. Insects, centipedes, millipedes, arachnids and crustaceans. They all have their own characteristics to belong in that particular class.

What are the 5 major classes of arthropods?

Arthropods are traditionally divided into 5 subphyla: Trilobitomorpha (Trilobites), Chelicerata, Crustacea, Myriapoda, and Hexapoda. Myriapoda is divided into four classes: Chilopoda (centipedes), Diplopoda (millipedes), Pauropoda, and Symphyla.

How many pairs of antennae do arachnids have?
