The Parasitiformes are a suborder of
Acari. Many species are parasitic (most famous of which are
ticks), but not all; for example, about half of the 10,000 known species in the suborder
Mesostigmata are predatory and
cryptozoan, living in the soil-litter, rotting wood, dung, carrion, nests or house dust. A few species have switched to grazing on
fungi or ingesting
spores or
pollen.
