The smallest entity universally recognised to be a living organism (not everyone considers the slightly smaller nanobes to be alive) is Nanoarchaeum equitans.

Is virus a living organism?
So were they ever alive? Most biologists say no. Viruses are not made out of cells, they can’t keep themselves in a stable state, they don’t grow, and they can’t make their own energy. Even though they definitely replicate and adapt to their environment, viruses are more like androids than real living organisms.
What is the largest living thing on earth?
More precisely, a specific honey fungus measuring 2.4 miles (3.8 km) across in the Blue Mountains in Oregon is thought to be the largest living organism on Earth. Several species of fungi belong to the Armillaria genus, which is popularly known as honey fungus.

How do viruses die?
Strictly speaking, viruses can’t die, for the simple reason that they aren’t alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can’t thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
Are viruses a life form?
Viruses are considered by some biologists to be a life form, because they carry genetic material, reproduce, and evolve through natural selection, although they lack the key characteristics, such as cell structure, that are generally considered necessary criteria for life.
Do viruses move?
Viruses aren’t actually alive – they don’t grow or move themselves, or eat or use energy, and they can’t reproduce on their own.
