who analysed the contents in the gut of C. glaucus it was found that the main component of its diet is that of coralline algae. Other research suggests a broader range of organisms within its diet including encrusting organisms (sponges, bryozoans etc.) and on diatoms and algae in a grazing type method. Predators, parasites, and diseases They have a variety of predators both invertebrate and vertebrate including sea stars, crabs, sea snails, birds, and fish. One of the main predators of green chiton are oystercatchers. All species of New Zealand oystercatchers prey on chiton from rocky shores. The birds have adopted a technique where they first, strike a sharp angled blow on the shell plates and if this does not dislodge the organism then the bird will apply pressure on the margin between the foot and the rock surface and use a scissor-like motion to release the grip. This is done until the organism is separated from the surface, and after the valves are taken off by the oystercatcher the chiton is eaten in one piece. Many species of chiton are susceptible to the parasite Minchinia chitonis. This releases spores into all tissue types of the chiton. It is unknown how, but the parasite is able to travel through the digestive tract and be excreted to prey on other chiton individuals. Research Recent analysis of the ultra structural and mechanical properties of the teeth present in that of Chiton glaucus and other organisms in the class Polyplacophora, one of the seven classes of mollusks, have shown to exhibit teeth of the most hardness and stiffness of any biomaterials known to date. This translates to as much as three times as hard as human enamel and the carbonate based shells of other mollusks. They achieve this feat through arranging a hard shell of organic incased and highly orientated magnetite rods that surround a soft core of organic rich iron phosphate in such a way that results in a tooth that is tough and wear resistant. By microscopically and spectroscopically analysing ultra structural features to figure out the structure/mechanical property relationships we can further our understanding relating to the architecture within the chiton tooth. The result of this would be wear resistant materials which could be developed for use in machines and tools, or coatings on medical implants and equipment. Chiton living on open coastlines are brighter in colour. They have richer
