A teaspoon of seawater typically contains about fifty million viruses. Most of these viruses are bacteriophages which infect and destroy marine bacteria and control the growth of phytoplankton at the base of the marine food web.

What is the most common marine virus?
The viruses, colored orange, are attached to the SAR11 marine bacteria, colored gray. The most common organism in the oceans, and possibly on the entire planet, is a family of single-celled marine bacteria called SAR11.
Are there viruses in sea water?
Every spoonful of seawater is filled with millions of viruses. And although most are harmless to people, they can infect a variety of marine life such as whales, crustaceans and bacteria.
What organisms in the marine environment do viruses infect?
Viruses were recognized as the causative agents of fish diseases, such as infectious pancreatic necrosis and Oregon sockeye disease, in the early 1960s [1], and have since been shown to be responsible for diseases in all marine life from bacteria to protists, mollusks, crustaceans, fish and mammals [2].
How many viruses are in a drop of seawater?
According to the scientists, there are approximately 10 million viruses in every drop of surface seawater, yet despite the high number of viruses very few are infectious agents to larger animals like fish, whales, or humans.
How many viruses are in the ocean?
Though they may seem insignificant, viruses are the most bountiful entities in the ocean. Just one millilitre of coastal water taken from the ocean's surface can contain up to 10 million viruses.
What are different types of marine viruses?
Tupanvirus Marine viruses/Representative species
Are marine viruses involved in the release of Dom?
1. Which one of the following statements about marine viruses is NOT true? A. They are involved in the release of DOM (dissolved organic matter) into the water.
Where do marine viruses come from?
The dominant hosts for viruses in the ocean are marine microorganisms, such as bacteria. Bacteriophages are harmless to plants and animals, and are essential to the regulation of marine and freshwater ecosystems are important mortality agents of phytoplankton, the base of the foodchain in aquatic environments.
