What are the microfauna?

microfauna are small animals and unicellular organisms visible only under the microscope. They are usually defined as a creature of less than 0.1 mm (100 microns) size, with mesofauna as organisms between 0.1 mm and 2 mm in size, although the definitions may vary.

In the soil, the microfauna can be found in large numbers - generally several thousand per gram. Anyone can take a little wet soil, put it under a microscope and find these organisms. Some of the most common and most important examples are Protozoa (unicellular eukaryotes), mites (among the most diverse and most successful and successful animals), springs (insect -related), immeatures (transparent worms), "worst nature)," They are also "the worst port beary)," which are also the worst "worst bearous" that are the worst, "microfauna can be found all over the world where there is wet land and other places. Springtails were foundNY in McMurdo Dry Valleys of Antarctica, One of the coldest and driest places on Earth.

Larger animals also found in the soil are called mesofauna, such as earthworms, arthropods and large immeasures and macropauna, which include mammal digging such as moths and rabbits. The microfauna is least understood about the life of the soil due to their small size and high diversity. Many of them are members of the so -called "Cryptozoa", animals that remain unwritten by science. Of the estimated 10-20 million animal species in the world, scientific names were only 1.8 million, and many remaining millions probably belong to this group, many of them in the tropics.

The microfauna lives in small pores between grains soil and many of them are water. Some are sessile, which means they attach to the substrate throughout their lives and never move. These animals fertilize their friends by releasing sperm with ciliated while they themselves remaineats in place. You can also find them on the human body and the average human home has thousands of mites that feed on the digestion of dead skin cells.
