Exoskeletons may undergo periodical moulting as the animal grows. Exoskeletons can be make of different materials including chitin (in arthropods), atomic number 20 compounds (in corals, mollusks) or silicate (for diatoms and radiolarians). The exoskelet on of insects is not provided a auspices ! hardly also as a surface for muscle attachment, as a watertight protection against drying and as a sense organ to interact with their environments. An external skeleton is quite morose in relation to the multitude of an animal, so their presence is only possible in fine animals or organisms. The exoskeleton can add up in macroscopical aquatic animals because of water pressure.
