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.
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.

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 ).
Marine Microbiology. Covering over 70% of the Earth’s surface, the Oceans represent an incredibly diverse, yet understudied ecosystem. In particular, microorganisms (bacteria, fungi, viruses and archaea) mediate key ecosystem processes in these marine systems and account for a majority of the biodiversity. These resilient microbial species ...
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?
As the first link in the food chain, they feed on a daily basis a large part of humanity at the other end of the trophic network. The marine microbiome is also an key part of the climate machine. It produces as much oxygen and absorbs more carbon dioxide than all the world’s forests. The ocean microbiome ensures the well-being of marine ...
