Dinoplax
Dinoplax is a genus of chitons, a group of marine molluscs with eight overlapping shell plates. They are commonly referred to as “polyplacophorans” or “coat-of-mail shells.” These fascinating creatures are characterized by their flattened, oval-shaped bodies and their ability to cling tightly to rocks and other hard surfaces. Dinoplax species can be found in the intertidal and subtidal zones of the Pacific Ocean, primarily along the coast of North America.
Characteristics
Dinoplax chitons possess several distinct characteristics:
- Eight overlapping shell plates: These plates, called "valves," are made of calcium carbonate and are arranged in a row down the back of the chiton, providing protection from predators.
- Girdle: A fleshy mantle surrounding the shell plates, which is often covered in spicules (tiny, sharp structures) for added defense.
- Foot: A muscular, flat foot that enables the chiton to move slowly along surfaces.
- Radula: A ribbon-like structure covered in rows of teeth, used for scraping algae and other food from surfaces.
- Gill slits: Located along the sides of the body, these slits are used for respiration.
Environments
Dinoplax chitons inhabit a variety of marine environments, including:
- Intertidal zones: The area between high and low tide marks, where they are exposed to air and waves.
- Subtidal zones: The area below the low tide mark, where they are permanently submerged.
- Rocky shores: They prefer hard surfaces like rocks and boulders to cling to.
