Microarthropods (from Micro… and Arthropods) are a special size group of small invertebrates of the phylum arthropods. Their sizes (usually from one to several millimeters) determine their habitats (usually soilsMicroarthropods // Explanatory Dictionary of Soil Science / ed. A. A.

Microarthropods are a diverse, taxonomically separate group of small animals, including representatives of various classes and orders of arthropods. Here are their main characteristics and features:
Microarthropods include mainly the following groups:
Many species of microarthropods have not yet been described and require further study.
Sizes: from fractions of a millimeter to several millimeters.
The body, like all arthropods, is segmented (with jointed limbs).
Microarthropods are found almost everywhere, most often in fallen leaves, soil litter and upper soil layers. They play an important role in accelerating the decomposition of organic matter and forming the soil structure.
In water, they are part of the plankton or .
There are predatory and parasitic species.
Microarthropod communities are bioindicators of environmental assessment, as they are very sensitive to changes in ecosystems. Their study helps to better understand the processes occurring in nature and assess the state of the environment.
Microarthropods of soils (pedobionts) are studied by soil zoologists (, and others).
