members of the class polyplacophora are known as CHITONS and are characterized by a shell that is divided into EIGHT segments
Chiton's are marine molluscs in the Polyplacophora class. They used to be known as Amphineura.
There are seven classes of mollusks. These are Gastropoda, Bivalvia, Polyplacophora, Scaphopoda, Cephalopoda, Aplocophora, and Monoplacophora.
Chiton are marine mollusks in the class of Polyplacophora. The adaptations they have include a wide foot for tight suction of rocks and a shell to protect themselves from drying out.

There are 93,000 named species of mollusk. Mollusks belong to the phylum Mollusca. There are four main classes of mollusk: 1) Cephalopoda; four types; Octopi, squids, cuttle fish, and the chambered nautilis 2) Bivalvia; four types; clams, oysters, scallopes, and muscles 3) Gastropada; gastropadas are snails and slugs 4) Polyplacophora; polyplacophora are chitons.
Major groups of mollusks include Bivalvia (clams, oysters, etc.), Cephalopoda (squids, octopii, cuttlefish), Gastropoda (snails, slugs), Polyplacophora (chitons), and several other minor or extinct classes.
Mollusca is a phylum that is classified under the super phylum Lophotrochozoa, in the Animal kingdom. There are 11 classes of mollusks in the Mollusca phylum.
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!**
Cephalopods (squid, octopus, cuttlefish), gastropods (snails and slugs), Bivalvia (clams, oysters, scallops, geoducks, mussels), Caudofoveata and Solenogastres, Polyplacophora (chitons) and Scaphopoda (tusk shells) all comprise this diverse group.
