Cyanoplax beanii is a species of chiton, a type of marine mollusk that is characterized by its eight overlapping shell plates, or valves. It is a relatively small species, typically reaching a maximum size of around 20 millimeters in length.
Description & Characteristics
Cyanoplax beanii exhibits a distinctive elongated, oval-shaped body with a characteristically flattened appearance. The dorsal surface is covered by eight overlapping, articulated valves that are typically brown or grayish-brown in color. The valves are adorned with fine, radiating lines, giving them a slightly textured appearance. The edges of the valves are often fringed with a thin layer of periostracum, a protective outer layer.
Habitat and Occurrence
Cyanoplax beanii is a marine species that is found in a variety of intertidal and subtidal habitats, including rocky shores, tide pools, and kelp forests. This species is predominantly found in the northeastern Pacific Ocean, ranging from Alaska to California. It is often found clinging to rocks and other hard substrates, where it can be found in depths ranging from the intertidal zone to approximately 50 meters. It is typically found in the neritic zone, a marine zone that extends from the shoreline to the edge of the continental shelf.
Taxonomy
Cyanoplax beanii belongs to the Class: Polyplacophora, which encompasses all chitons. This class is further subdivided into the Order: Chitonida, which includes the majority of chiton species. Cyanoplax beanii is classified within the Family: Tonicellidae, which includes a diverse array of chiton species, many of which are found in the intertidal zone.
Feeding
Cyanoplax beanii is a herbivorous species, feeding primarily on algae and other plant matter that grows on rocks and other hard substrates. It uses a specialized tongue-like structure called a radula to scrape algae from surfaces. The radula is covered with tiny, tooth-like structures called denticles, which are used to grind and break down food.
