Although the ancestral domestic of chelicerates used to be the ocean, nearly all of smooth species live to tell the tale land. such a lot scholars of spiders and mites additionally limit themselves to terrestrial habitats. although, a stunning variety of mites (Arachnida: Acari) have again to a watery lifestyles. nearly 7000 species from the Mesostigmata, Astigmata, Oribatida, and particularly the Prostigmata, now stay in marine and freshwater habitats. In Aquatic Mites, a dozen chapters discover the distribution, ecology, habit, genetics, and evolution of the main varied of those outstanding arachnids. the result of those stories bring up as many fascinating questions as they resolution, and will galvanize extra investigations of the biology of freshwater and marine Acari.

Results Number of genera and species Table I includes 1018 halacarid species in 51 genera. Copidognathus is the genus most rich in species, the 336 species comprising 33% of all marine halacarid species. The genus is eurytopic. Although feeding has not been observed, many may feed on bacteria and fungi. The genus Rhombognathus currently includes 93 species, equalling 9% of all hal acarid species. As demonstrated by the green colour of the gut, phytophagy is the most important way of feeding.

Data from greater depth and comparable substrata but different latitudes are lacking. Is there a latitudinal diversity cline, with an increase of species richness with decreasing latitude, as postulated by Brown (1988) and Rosenzweig (1997)? Comparison of data (Table 2) from temperate and tropical waters demonstrate, more halacarid genera are recorded from the temperate provinces than from the tropics, fourteen genera are exclusively temperate, five genera tropical; three of the latter are mono typic, collected just once, and hence their life style is hardly known.
