These chitons can be found in intertidal zones to 40m depths. Heavy waves on rocky shores are favorable. K. tunicata is unique compared to other chitons in that it tolerates direct sunlight. These intertidal zones are susceptible to contamination from industrial activities, timber harvesting, mining, seafood processing, as well as coastal ...
Chitons are generally herbivorous grazers, though some are omnivorous and some carnivorous. [34] [35] They eat algae, bryozoans, diatoms, barnacles, and sometimes bacteria by scraping the rocky substrate with their well-developed radulae. A few species of chitons are predatory, such as the small western Pacific species Placiphorella velata ...

Some coralline algae develop into thick crusts which provide microhabitat for many invertebrates.

This is probably an important factor ...

Types of substrate attachments include mussels' tethering byssal threads and glues, sea stars' thousands of suctioning tube feet, and isopods' hook-like appendages that help them hold on to intertidal kelps. Higher profile organisms, such as ...

Not all algae are microscopic.
