Small, single-celled organisms called bacteria exist.
Nearly all areas of the world are home to bacteria, which are essential to their ecosystems.
Some species can survive in environments with high pressure and temperatures.
In fact, it's thought that there are more bacterial cells in the human body than there are human cells.
Bacterial nomenclature
Nomenclature of bacteria refers to naming, and Carl Linnaeus established the binomial system, which is used to name bacteria and other species (1674-1748).
This means that both the genus and specific names must be italicized.
The names are also Greek or Latin in origin.
The genus name must start with a capital letter, while the species name must start with a lowercase letter.
The particular epithet is an adjective that must coincide with the genders of the generic name Organisms and epithets should be Latin or Latinized.
