No, a chiton is not an ecdysozoan. An ecdysozoan (clade Ecdysozoa) is an organism that sheds/molts its tough external coat (cuticle) as it grows up. Chitons are soft bodied organisms that secrete a hard, protective shell made up of calcium carbonate with eight dorsal plates. They belong to the Class Polyplacophora which belongs to the Phylum Mollusca.

(so you can see the classification easier...in case it was confusing):

---Clade Eumetazoa

-- Phylum Mollusca

- Class Polyplacophora

**Phylum Mollusca is NOT the only phylum within that clade! There are other phylums/classes/lineages belonging to the clade too!**
