Marine microorganisms make up about 70% of the total marine biomass. It is estimated marine viruses kill 20% of the microorganism biomass every day. Viruses are the main agents responsible for the rapid destruction of harmful algal blooms which often kill other marine life.
They can infect all types of life forms, from animals and plants to microorganisms, including bacteria and archaea. Marine viruses are defined by their habitat as viruses that are found in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries.

Marine biology is the scientific study of the biology of marine life, organisms in the sea. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy . A large proportion of all life on Earth lives ...
Marine life, sea life, or ocean life is the plants, animals, and other organisms that live in the salt water of seas or oceans, or the brackish water of coastal estuaries. At a fundamental level, marine life affects the nature of the planet.
Sep 27, 2023 · Viruses are ubiquitous in the oceans, exhibiting high abundance and diversity. Here, we systematically analyze existing genomic sequences of marine prokaryotes to compile a Marine Prokaryotic...
Jun 28, 2020 · A study released in 2019 identified almost 200,000 types of marine viruses -- and few of them had ever been seen before. They were split into five major groups, generally based on their specific habitats. But many types were found around the entire planet. Viruses affect all forms of marine life, including fish, crustaceans, and mammals.
Sep 28, 2018 · Viral abundance in the ocean has been estimated at 10 30 virions, one or two orders of magnitude greater than the estimated number of bacterial and eukaryotic cells, so viruses are the most abundant life in the oceans.1, 2 Marine mammals live in intimate contact with the ocean, and therefore a vast diversity of viruses. Advances in molecular ...
