Virus
Viruses are the smallest microbes known that cause disease. They are sub-microscopic. This means that they can not be seen with a regular microscope because they are too small (measured in nanometers). It takes an electron microscope to see a virus particle. The second microbe that is among the smallest would be bacteria and then probably protists, as a generalization, after that (protists and bacteria have wider ranges of sizes than viruses). Bacteria are microscopic living organisms, while the viruses are non-living sub-microscopic organisms. Protists are single-celled living organisms, such as protozoa.
As of now, the smallest bacteria on Earth are those belonging to Mycoplasma.
The smallest organisms are bacteria.
No, infact nerve cell is the longest cell . PPLO is the smallest cell.

if you want the smallest living animal, it's the amoeba, its classified under protozoa in the animal kingdom
microscopic plankton
Nanoarchea is the name of the smallest bacteria:)
Bacteria is the smallest cell*it was in my science book*
a microscopic meteoroid

Zooplankton. It's a microscopic invertebrate.
