European Science Foundation, 2012 : 14 The range of sizes shown by prokaryotes (bacteria and archaea) and viruses relative to those of other organisms and biomolecules Under a magnifier, a splash of seawater teems with microscopic life Microscopic life undersea is diverse and still poorly understood, such as for the role of viruses in marine ecosystems. Most marine viruses are bacteriophages ...
Invisible to the naked eye, there is a teeming world of microbes living in the ocean with a complexity and diversity that rivals all other life on Earth. They include bacteria, viruses, archaea, protists, and fungi. If you weighed all the living organisms in the ocean, 90 percent of that weight would be from microbes.

Jun 4, 2016 · 1 Introduction. Bacteria and Archaea represent major drivers of the biogeochemical cycles in the marine environment due to their large abundance, high cell-specific activity, and their unique metabolic capabilities that include, among others, nitrogen fixation, (anaerobic) ammonia oxidation, and methane oxidation.

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 ...
Introduction. Marine animals are the icons of life in the oceans. They represent about two million species (Mora et al., 2011) and include a wide range of body designs, from the highly simplistic sponges lacking true tissues and organs to the complex vertebrates containing specialized tissues and organs, such as fish and marine mammals, with some iconic representatives presented in F igure 1.
