predators during daylight hours. This is compared to being found on stones and cobbles in more exposed areas. This chiton is able to survive in muddy areas, particularly estuaries. Surprisingly it is also able to live in areas were the substrate is semi-polluted. Life cycle Little is known about the habits of chiton in general but observations have been made to further understand the processes relating to spawning amongst other processes. Early research conducted by a member of the great barrier reef investigation in Queensland saw that a common chiton of this area seemed to every time choose a night of full moon to conduct its spawning. This also depended on the conditions at the time as if they were not favourable or the sea was rough, spawning would not occur and was delayed until the next full moon. This was the case even if in between full moons was a favourable time period where the weather was right. It has since been shown that the spawning of chiton is usually synchronous but not necessarily correlated with any particular stage of the lunar or solar cycle. Generally chitons have separate sexes and sperm and eggs are spawned through a simple gonad near the posterior end of the foot. Chitons do not have a free swimming larval stage so distribution of the organism is not particularly great. Once the egg has been released through the anus it moves through currents into plankton where it hatches after about 2 days. Next metamorphosis occurs to promote larval settlement. The changes are not dramatic but it does start the biomineralisation of the valves and radula present in the adult stage. After this the prototroch and apical tuft are cast off and the shape of the organism changes from elongated to oval in outline about 0.5 mm in length with only seven calcareous valves. A month later the eighth valve becomes apparent and two red larval spots present themselves which are lost when the organism reaches maturity. The process then repeats if the organism reaches maturity through avoiding both invertebrate and vertebrate predators. Diet Chiton glaucus show clear daily patterns of activity; they remain hidden during the day to escape visual predators and then during the night they travel to the tops of the rock to feed on the algae that has grown there since the previous night.
