Acanthochitonidae chitons are found in a variety of marine habitats, including rocky intertidal zones, coral reefs, and seagrass beds. They are also found in deep sea environments, with some species occurring as deep as 3,000 meters. Acanthochitonidae chitons are known to be active grazers, feeding primarily on algae and detritus.
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 ...
Like other chitons, it is a slow moving grazer that consumes several species of brown and red algae including kelps, sea lettuce, and encrusting diatoms. They're also known to eat sponges , tiny barnacles , spirobid polychaetes , and bryozoans .
Chiton glaucus, common name the green chiton or the blue green chiton, is a species of chiton, a marine polyplacophoran mollusk in the family Chitonidae, the typical chitons. It is the most common chiton species in New Zealand .
While larger chitons have been known to eat large algal blades, encrusting colonial animals, or even engage in predatory behavior to trap and consume mobile animals, Acanthochitona zelandica is a grazer and uses the radula to scrape algal films and built-up diatom layers off of tidal rocks.
What to know about the toxic bloom.
The white Plaxiphora chiton reaches a common size of about 95mm, with a minimum and maximum length of 40–100 millimetres (1.6–3.9 in) and a width of 25–38 millimetres (0.98–1.50 in). The shell of this large chiton is dark green to brown, humped and oval shaped, with eight rough valves.
Animals out of water only have about 73% the respiration of submerged animals, and likely incur an oxygen debt while out of water that must be repaid once resubmerged. [4] When submerged, gas exchange occurs by water flowing from the anterior portion of the chiton into the mantle cavity where the ctenidia (gills) reside in the pallial grooves.
