All chitons bear a protective dorsal shell that is divided into eight articulating aragonite valves embedded in the tough muscular girdle that surrounds the chiton's body.

Nov 12, 2024 · Chitons are flattened, bilaterally symmetrical mollusks armored with eight calcified plates on their shell. They constitute the class Polyplacophora and are hence known as polyplacophorans. Sometimes, they are also called by the names sea cradles, coat-of-mail shells, suck-rocks, and loricates.

Chitons use a large, flat foot for creeping along and clinging to rocks; they also have a well-developed radula (filelike structure) with which to scrape algae and other plant food from rocks. On either side of the foot is a groove containing the gills.

May 27, 2024 · Chitons form part of the class Polyplacophora, which refers to marine creatures from the Mollusk family. This complex word is Latin for “many plates.” The class consists mainly of chitons, with 8 plates or valves overlapping on their elongated and slender shells.

Aug 16, 2020 · 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 …

Chiton has an oval and dorso-ventrally flattened body. The dorsal side is convex and the ventral side is flattened. The middle portion of the dorsal side is covered over by eight overlapping pieces of calcareous shells arranged antero-posteriorly (Fig. 16.5A).

In this article we will discuss about the structure of Chiton with the help of a diagram. 1. It is a marine animal of cosmopolitan distribution. 2. It is found attached to stones and rocks (coral reefs) between tide marks. 3. Body is elliptical and is convex on dorsal and flat on ventral surface.

The chiton has eight plates, and underneath the plates is a muscular foot that moves the chiton over rocks and other structures, both in and out of the water. It also has a tongue -shaped structure called the radula, which has many rows of 17 teeth each.

Chitons have a shell that is composed of eight separate shell plates or valves. These plates or valves overlap slightly at the front and back edges of the chitons and yet they articulate well with each other.

Chitons (Mollusca, Polyplacophora) are a promising system for studies of biomineralization because they build a range of calcified structures including shell plates and spine- or scale-like...
