In excess of 3,000 species of animal-parasitic nematodes have been recorded and every vertebrate that has been studied in detail acts as a host for at least one, and frequently several, nematode species. The nematodes range in size from the microscopic (<1mm) to the 'gigantic' (>9m). Traditionally the animal- parasitic nematodes have been included in six groups (taxonomic orders), although this phylogeny has recently been questioned. Some orders exclusively contain animal parasites, whereas others have only a few representatives. Many have life cycles in which they directly infect their host, although adaptations to encourage transmission between hosts are common, whereas others utilise an intermediate host to achieve transfer. The biology, pathology, epidemiology and control of representatives from each of the groups are presented. Emphasis is given to the economically significant parasites of medical and veterinary importance, but other species are included where they illustrate particular biological features. The text and numerous accompanying photographs, figures, and tables provides an easily understood introduction to nematodes that parasitise animals and humans
