What is the percentage of bacteria in the world?
Using several statistical approaches, we estimate that there exist globally about 0.8–1.6 million prokaryotic OTUs, of which we recovered somewhere between 47%–96%, representing >99.98% of prokaryotic cells.
How much do all the bacteria in the world weigh?
No? Well, scientists definitely do and a new study published in the Proceedings of the National Academy of Sciences offers the surprising answer. Every living thing on Earth — from the tiniest bacteria to a mighty redwood tree — weighs a combined 550 gigatons when removing water from the equation.
Are there more bacteria or viruses?
Biologists estimate that 380 trillion viruses are living on and inside your body right now—10 times the number of bacteria.
How many virus species exist?

Where can bacteria be found on the Earth?

How big can a bacteria grow to be?
Although most bacteria only measure from 0.5 to 2.0 micrometers, some can grow large enough (600 microns) to be observable to the human eye. Bacteria are prokaryotes, which means they do not have nucleated cells like plants and animals.
