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.
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? The marine environment—particularly the ocean—is the largest continuous habitat on Earth.

Genomic Era. Future. Introduction. Marine microbes are abundant and diverse. But their tiny size means they are not easy to study. First observed in 1675, marine microbes were not cultured in the lab for over 100 years allowing for further observation.
Jul 29, 2022 · Archaeal lipids are ubiquitous in marine sediments and are commonly used to infer past marine sea surface temperatures. However, these molecules can also be used to investigate the ecological and evolutionary history of marine archaea.
Jun 4, 2016 · Marine microscopic life varies from single-celled organisms, simple multicellular, to symbiotic microorganisms encompassing all three domains of life: Bacteria, Archaea and Eukarya as well as biologically active entities such as viruses and viroids. Together they form the Ocean’s “microbiome”.
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 is any microscopic living organism or virus, that is too small to see with the unaided human eye without magnification.
