Taxonomy

Acanthochitona avicula is classified within the phylum Mollusca, belonging to the class Polyplacophora, the order Chitonida, and the family Acanthochitonidae. This classification reflects the evolutionary relationships and shared characteristics of this species with other chitons.

Feeding

Acanthochitona avicula is a herbivorous species that feeds on algae. It uses its radula, a tongue-like structure with rows of teeth, to scrape algae off rocks and other surfaces. The chitons’ strong, muscular foot allows them to cling tightly to rocks in strong currents. The feeding habits of Acanthochitona avicula play an important role in controlling algal growth in its habitat.
