Microfauna

Microfauna (Ancient Greek mikros "small" + New Latin fauna "animal") refers to microscopic organisms that exhibit animal-like qualities. Microfauna are represented in the animal kingdom (e.g., nematodes, small arthropods) and the protist kingdom (i.e., protozoans). This is in contrast to microflora which, together with microfauna, make up the microzoa.
