Acanthochitona hirudiniformis is a species of chiton, a type of marine mollusk with a shell divided into eight plates. It is a relatively common and widespread species, found in a variety of habitats throughout its range.
Description & Characteristics
Acanthochitona hirudiniformis is characterized by its elongated, somewhat flattened body, which can grow up to 30 mm in length. Its shell is typically a reddish-brown color, but can vary in shade depending on the environment. The shell is covered in small, raised bumps, giving it a rough texture. Like other chitons, Acanthochitona hirudiniformis has a strong, muscular foot, which it uses for locomotion. It also possesses a pair of sensory tentacles near its head, which it uses to detect its surroundings.
Habitat and Occurrence
Acanthochitona hirudiniformis is a marine species that prefers to live in intertidal and subtidal zones, with a depth range extending to 30 meters. It is typically found attached to rocks, algae, and other hard substrates. This species is commonly found in rocky shores, kelp forests, and other coastal habitats. Acanthochitona hirudiniformis is a common inhabitant of the sublittoral zone, the area of the seabed extending from the low tide mark to the edge of the continental shelf, and is often found in the infralittoral zone, the portion of the sublittoral zone closest to the shore.
Taxonomy
Acanthochitona hirudiniformis belongs to the Class: Polyplacophora, Order: Chitonida, and Family: Acanthochitonidae. The class Polyplacophora includes all chitons, and they are distinguished by their eight-plated shells. The order Chitonida encompasses the vast majority of chiton species, and the family Acanthochitonidae is characterized by the presence of sharp, pointed scales on their shells.
Feeding
Acanthochitona hirudiniformis is a herbivore that feeds primarily on algae, scraping it off rocks and other surfaces with its radula, a rasping tongue-like structure. It is an important part of the marine ecosystem, helping to control algae populations and provide food for other organisms.
