Micro-animals are animals so small that they can only be visually observed under a microscope. Unlike most other microorganisms, which are unicellular, micro-animals are multicellular, like all other animals.
Notable phyla include:
- Microscopic arthropods, including dust mites, spider mites, and some crustaceans such as copepods and certain cladocera.
- Tardigrades ("water bears")
- Rotifers, which are filter feeders that are usually found in fresh water.
- Some nematode species[1]
- Many loricifera, including the recently discovered anaerobic species, which spend their entire lives in an anoxic environment.[2][3]
