Introduction,is generally abundant on the earth’s surface, but it may be locally scarce, and the reflexion of these facts upon the structure, function and distribution of terrestrial arthropods, is the concern of this book.

Water Content, of animal tissues, water content expressed as a precentage of total weight is very much less than its mole fraction—about 70%. In fact, as Table 1 shows, water content is very variable, both within and between species of arthropods, and we may briefly consider the reasons for such variability.

,Water Loss—Respiratory, oxygen is absorbed from the gaseous phase, are moist, probably because the rate of diffusion of oxygen through water is some 34 times more rapid than through “chitin” (Dejours, 1975). Respiratory surfaces, essential for life as they are, therefore constitute a potential site for dehydration in land

Excretion and Osmoregulation,nd ionic regulation, and it is, therefore, convenient to consider these processes together. However, we shall treat nitrogen elimination separately because this is a general problem for all arthropods and one which stands somewhat apart from other aspects of water balance.
