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!**

Ecdysoans belong to the clade Ecdysozoa. This clade includes animals that shed/molt a tough external coat (known as a cuticle) as they grow up. The two largest phyla in this clade are Phylum Nematoda and Phylum Arthropa. Within Phylum Arthopoda is the Subphylum Hexopoda, which contains the Class Insecta. Insects (as you may have guessed already), are in this class, and since a cricket is an insect, they are indeed an ecdysozoan.
