Mopalia ferreirai is a species of chiton, a type of marine mollusc characterized by its eight overlapping shell plates. It is known for its distinctive features and its relatively common occurrence in certain marine habitats.
Description & Characteristics
Mopalia ferreirai is a medium-sized chiton, typically reaching a maximum size of around 50 mm. Its body is oval-shaped and somewhat flattened, covered by eight articulated plates, known as valves. The plates are often adorned with fine lines and ridges, and the overall coloration can vary, ranging from brown to reddish-brown. The chiton’s mantle, the fleshy tissue surrounding the shell plates, is often covered in small, hair-like structures called spicules.
Habitat and Occurrence
Mopalia ferreirai is predominantly found in intertidal and subtidal zones of the Pacific Ocean. This species is particularly common in rocky habitats, often clinging to the underside of rocks or amongst algae. Its depth range extends from the low tide mark down to approximately 100 meters. The distribution of Mopalia ferreirai spans several marine zones, including the Neritic zone, characterized by its relatively shallow waters, and the deeper Mesopelagic zone.
Taxonomy
Mopalia ferreirai belongs to the Class: Polyplacophora, Order: Chitonida, and Family: Mopaliidae. These taxonomic classifications place it within a group of marine mollusks characterized by their unique eight-plated shells and their ability to cling tightly to surfaces.
Feeding
Mopalia ferreirai is a herbivorous chiton, feeding primarily on algae that grows on rocks and other substrates. It uses its radula, a ribbon-like structure covered with rows of teeth, to scrape algae off surfaces. This feeding behavior contributes to the important role chitons play in marine ecosystems, helping to control algae growth and maintain biodiversity.
