Most chitons feed by rasping algae and other encrusted food off of the rocks on which they crawl. One genus is predatory, trapping small invertebrates under the fringe of the mantle, and then eating the captured prey. In some chitons, the radula has teeth tipped with magnetite, which hardens them.

What do most chitons feed on?
Most chitons are herbivorous and feed on algae and other sedentary organisms, including sponges, bryozoans, and coelenterates, which they scrape off the substrate or devour using a tongue-like organ, set with teeth (radula), which can be protruded and then retracted.
What is a chiton what and how do they eat?
Chitons are generally herbivorous grazers, though some are omnivorous and some carnivorous. They eat algae, bryozoans, diatoms, barnacles, and sometimes bacteria by scraping the rocky substrate with their well-developed radulae.
How do chitons survive?
Chitons are adapted to living on hard rock surfaces. They have a very muscular foot, and when disturbed, can clamp down so that they cannot be dislodged unless their shell is smashed.
Do Polyplacophora have tentacles?
They have no foot or shell, and the epidermis secretes chitinous scales or spicules. They have no eyes or tentacles, and the radula is either reduced or absent.
Can chitons be eaten?
Chitons were prepared in many different ways. The Tlingit ate them raw, or dried for winter [8]. Port Simpson people consumed raw chitons that had been soaked in salt water for several days. In addition, chitons were steamed and eaten with animal fat or roasted on a fire [14].
How does the chiton eat?
Most chitons feed by rasping algae and other encrusted food off of the rocks on which they crawl. One genus is predatory, trapping small invertebrates under the fringe of the mantle, and then eating the captured prey. In some chitons, the radula has teeth tipped with magnetite, which hardens them.
How do you use a chiton?
Blouse the hem of the chiton until it comes just above the person's knees. Wrap the cloth around the person's body, like with a chiton, but only pin the cloth over his right shoulder. That's it. This piece of clothing is a simple cloak.
What do gumboot chiton eat?
Diet in the Wild: Nocturnal grazers feeding mainly on red algae, but they will eat young kelp or green algae. Natural Predators: The gumboot chiton's larval stage is vulnerable to numerous predators but adults are most likely prey for some species of sea stars. River otters are reported to eat them, too.
What are 3 characteristics of Polyplacophora?
The main characteristics of Polyplacophora include (1) elongate or oval, dorsoventrally flattened, bilaterally symmetrical, marine; (2) with dorsal shell of eight plates embedded in a tough mantle; (3) mantle-edge stiffened (called the girdle); (4) large, muscular, ventral foot (girdle and foot can act as suction cup); ...
Does Polyplacophora have mantle cavity?
They have an elongated oval body. Dorsally, the mantle bears eight shell valves. ... The mantle skirt extends around the whole periphery of the animal as a girdle (Polyplacophora-transverse sec.). The ventral surface is mainly occupied by the muscular foot, which is surrounded by the mantle cavity.
How do chitons defend themselves from predators?
The distinctive feature of all chitons is their eight overlapping plates, which protect them from predators and strong crashing waves. When disturbed they use their muscular, mucus-secreting foot to clamp down hard on rocks, making them difficult to dislodge.
Do chitons eat algae?
Chitons eat algae, bryozoans, diatoms, barnacles. ... Nearly all chitons are grazing herbivores. The radula is used to scrape microscopic algae and even bacteria off the rocks they are grazing. A few species of chitons are predators eating other small invertebrates, such as shrimp and possibly even small fish.
How do chitons breathe?
Because the chiton mantle is stiff and surrounds the body, it is referred to as a girdle. ... Inside the groove are gills that help the chiton to breathe underwater. Oxygen-carrying water enters the grooves near the head, flows through the gills, and exits at the rear of the body.
