Chaetopleura angulata, commonly known as the Chiton, is a species of marine mollusk belonging to the class Polyplacophora, commonly known as chitons. These fascinating creatures are characterized by their unique, eight-plated shells that cover their dorsal surface.
Description & Characteristics
The Chiton is a relatively small species, reaching a maximum size of approximately 25 millimeters in length. Its shell is typically brown or grayish in color, with a distinctive angular shape, hence the species name “angulata.” The plates are joined together by a flexible girdle, which is covered with numerous spicules (small, pointed structures) that help the animal to adhere to surfaces.
Habitat and Occurrence
Chaetopleura angulata is a common inhabitant of the intertidal zone and shallow subtidal waters. The Chiton is particularly prevalent in rocky environments, where it can be found clinging to rocks and other hard surfaces. The species is known to inhabit both the Neritic Zone, which extends from the shoreline to the edge of the continental shelf, and the Oceanic Zone, covering the vast expanse of open ocean beyond the continental shelf.
Taxonomy
Chaetopleura angulata is scientifically classified within the phylum Mollusca, specifically belonging to the Class Polyplacophora, the Order Chitonida, and the Family Chaetopleuridae. The species is part of a diverse group of marine invertebrates that exhibit a wide range of adaptations for life in the intertidal and subtidal regions.
Feeding
The Chiton, Chaetopleura angulata, is a herbivorous species, primarily feeding on algae that it scrapes from rocks using its radula, a specialized feeding structure. Its diet may also include barnacles and foraminifers, although reliable information about these specific food sources is limited.
