Acanthochitona defilippii is a species of marine mollusk belonging to the class Polyplacophora, commonly known as chitons. These fascinating creatures are characterized by their eight overlapping shell plates, which provide them with remarkable protection. Acanthochitona defilippii, specifically, is a member of the Acanthochitonidae family, known for their spiky, often colorful shells.
Description & Characteristics
Acanthochitona defilippii exhibits a distinctive morphology. The shell, composed of eight articulated plates, is typically oval-shaped and displays a rough, granular texture. The coloration can range from dark brown to a mottled pattern of brown and white. The undersurface, known as the girdle, is covered in numerous minute spines that aid in locomotion and defense.
Habitat and Occurrence
Acanthochitona defilippii is a benthic species, meaning it is found on the seafloor. This chiton is a common inhabitant of rocky intertidal zones, preferring areas with moderate wave action. Their preferred habitat is typically characterized by the presence of algae and other marine organisms. This species is often found in the sublittoral zone, which extends from the low tide mark to the edge of the continental shelf.
Taxonomy
Acanthochitona defilippii belongs to the class Polyplacophora, a group of mollusks known for their unique shell structures. The species falls under the order Chitonida, which encompasses a diverse range of chitons, and the family Acanthochitonidae, known for their spiky shells.
Feeding
Acanthochitona defilippii is a herbivore, feeding primarily on algae that grow on rocks and other substrates. They use their radula, a tongue-like structure covered in teeth, to scrape algae off the surface. This feeding behavior plays an important role in maintaining the ecological balance of their habitat.
