A classic example of amensalism is the microbial production of antibiotics that can inhibit or kill other, susceptible microorganisms. A clear case of amensalism is where sheep or cattle trample grass. Whilst the presence of the grass causes negligible detrimental effects to the animal's hoof, the grass suffers from being crushed.
Many microfauna are members of the so-called cryptozoa, animals that remain undescribed by science. Out of the estimated 10–20 million animal species in the world, only 1.8 million have been given scientific names, and many of the remaining millions are likely microfauna, much of it from the tropics.
