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.
Marine phages parasite marine bacteria and archaea, such as cyanobacteria. They are a common and diverse group of viruses and are the most abundant biological entity in marine environments, because their hosts, bacteria, are typically the numerically dominant cellular life in the sea.

Jan 13, 2021 · Members of the domain Archaea are now known to have diversified and radiated into a variety of disparate habitats in both aquatic freshwater, marine, and terrestrial environments. When the Archaea were first recognized via phylogenetic analyses of ribosomal RNA sequences of pure cultures ( Woese and Fox, 1977; Woese, 1987 ), they appeared at ...

May 16, 2017 · Extremophiles belonging to the Eubacteria, Archaea, and Eukarya kingdoms produce extremophilic biomass in ecological niches such as oceans, salt marshes, solar salterns, hypersaline lakes, hot springs, marine hydrothermal vents, and soda lakes. These marine polye-xtremophiles have great importance and contributed a lot in biotechnological ...

Mesophilic archaea discovered in the marine water column Prior to 1992, archaea were thought to exist as one of three types—either an extremist that lives in very salty environments (a halophile), an extremist that lives in scalding hot water (a thermophile), or as a methane producer (a methanogen).
A critical property of seawater is that it contains a large amount of salt and that this requires microorganisms that live in it are able to adjust their osmotic pressure. The marine microbiome is composed of the three domains of life: bacteria, archaea, and eukarya, as well as viruses, all of which in dazzling numbers and diversity.
