e. Marine microorganisms are defined by their habitat as microorganisms living in a marine environment, that is, in the saltwater of a sea or ocean or the brackish water of a coastal estuary. A microorganism (or microbe) is any microscopic living organism or virus, which is invisibly small to the unaided human eye without magnification.
These microorganisms that live near the ocean surface and convert carbon dioxide into organic carbon via photosynthesis. They produce much of the oxygen we breathe and are the base of the marine food chain. They also play an important role in drawing heat-trapping carbon dioxide from the atmosphere into the ocean.

Marine animals share the sea with a vast diversity of microorganisms, including protists, bacteria, archaea, fungi, and viruses which comprise millions of cells in each milliliter of the 1.3 billion km 3 of water comprising the oceans ( Eakins and Sharman, 2010 ).
Lokiarchaeota found in a deep-sea hydrothermal vent show an evolutionary link between archaea and the more complex eukaryotes. After examining the archaeal DNA, researchers discover that these microbes share about 100 genes for complex cellular functions with eukaryotes, suggesting they are the closest living prokaryotic relatives of eukaryotes.
This chapter investigates what justifies marine microbiology as a discipline in its own right. Do marine microorganisms really exist? And if so, what distinguishes them from freshwater- or terrestrial microorganisms, or from microorganisms living in any other specialized habitat?
t. e. Marine prokaryotes are marine bacteria and marine archaea. They are defined by their habitat as prokaryotes that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. All cellular life forms can be divided into prokaryotes and eukaryotes.
