The Parasitiformes are an order of Acari (treated as a suborder and superorder in outdated classifications). Many species are parasitic (most famous of which are ticks) but not all; for example about half of the 10000 known species in the suborder Mesostigmata are predatory and cryptozoan living in the soil-litter rotting wood dung carrion nests or house dust.
