What are the different families of polyplacophora?
The main families include Lepidopleuridae, Hanleyidae, Ischnochitonidae, Callochitonidae, Schizochitonidae, Mopaliidae, Chitonidae, and Acanthochinonidae. Chitons (phylum Mollusca, class Polyplacophora) and limpets (phylum Mollusca, class Gastropoda) also produce teeth for grinding the rocky substrate in order to extract the algae.
Where do polyplacophorans live in the ocean?
Polyplacophorans are bottom dwelling animals. With over 1,000 species chitons are a diverse and successful class of molluscs. Seen from above they are a flattened, elongated oval shape. They are found on algae and on sandy substrates, but mostly on harder surfaces such as rocks and corals.
How are polyplacophorans different from limpets and limpets?
Polyplacophorans are a class of the phylum Mollusca and are commonly known as Chitons. They are easily distinguishable from the superficially similar Limpets (which are part of the Gastropoda) by the fact that their shell is composed of eight separate plates, rather than being just one piece.
Where are the ctenidia located in a Polyplacophora?
Polyplacophorans breath by means of ctendia (a sort of gill structure). These ctenidia are located inside the mantle cavity and towards the rear of the animal. They are paired, meaning there is always the same number on each side of the animal’s body.
