The Acanthochitonidae, also known as the “spiny chitons,” are a family of marine mollusks in the order Polyplacophora. They are characterized by their eight overlapping shell plates, which are often adorned with spines or tubercles. Acanthochitonidae is a diverse family with numerous species found worldwide, particularly in tropical and subtropical regions.
Members of Acanthochitonidae are typically small to medium-sized chitons, with shell lengths ranging from a few millimeters to several centimeters. Their shells are characterized by their strong, prominent spines or tubercles, which can be arranged in rows or clusters. The shell plates are also often adorned with intricate patterns and colors, contributing to their distinctive appearance.
The girdle, the fleshy band that surrounds the shell, is typically covered in scales or spicules. This girdle plays a crucial role in the chiton's ability to adhere tightly to rocks and other surfaces. Acanthochitonidae chitons possess a radula, a specialized feeding organ that allows them to scrape algae and other organic matter from the substrate.
Acanthochitonidae species are predominantly found in intertidal and subtidal zones, inhabiting rocky shores, reefs, and kelp forests. They are adapted to life in these environments, demonstrating a strong ability to cling tightly to rocks and other hard surfaces using their powerful muscular foot.
While the scientific name "Acanthochitonidae" is the most widely recognized, common names for this family of chitons include:
