There are around 40 different species of sea stars that have been affected by this disease. In 2014 it was suggested that the disease is associated with a single-stranded DNA virus now known as the sea star-associated densovirus (SSaDV); however, sea star wasting disease is not fully understood.

Viruses are the most abundant life in the ocean, harboring the greatest reservoir of genetic diversity. [256] As their infections are often fatal, they constitute a significant source of mortality and thus have widespread influence on biological oceanographic processes, evolution and biogeochemical cycling within the ocean.

Orthopoxvirus particles. A DNA virus is a virus that has a genome made of deoxyribonucleic acid (DNA) that is replicated by a DNA polymerase.They can be divided between those that have two strands of DNA in their genome, called double-stranded DNA (dsDNA) viruses, and those that have one strand of DNA in their genome, called single-stranded DNA (ssDNA) viruses. dsDNA viruses primarily belong ...
Chrysochromulina is a particularly important genus as it can comprise more than 50% of the photosynthetic nanoplanktonic cells in the ocean. [36] Little is known about the life cycle of the virus infecting these flagellate-containing planktonic species, Chrysochromulina brevifilum and C. strobilus. Suttle and Chan (1995) were the first to ...
Some members of this family can have a linear double-stranded DNA while others have a circular double stranded DNA. The genome has been found to be up to 560 kilobases in length. Up to 50% of the DNA can be represented by guanine or cytosine. This virus is known to infect algae, which means it is found in the ocean. [26]
The viruses that store their genomic information using DNA, DNA viruses, are the best studied subgrouping of algae-infecting viruses This is especially true for the dsDNA virus family, Phycodnaviridae. [1] [3] However, other groups of dsDNA viruses including giant viruses belonging to the family Mimiviridae also infect algae. [3]
Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal wetlands, lagoons ...
Coccolithovirus is a genus of giant double-stranded DNA virus, in the family Phycodnaviridae. Algae, specifically Emiliania huxleyi , a species of coccolithophore , [1] serve as natural hosts. There is only one described species in this genus: Emiliania huxleyi virus 86 .
