Classification
Because virus oppose the The Cell Theory, thus, it doesn't fits into the three domain system of biological classification. However,the discovery of Pandoravirus salinus lead scientist to think about the possibility of the existence of the fourth domain of life, other than Archean, Bacteria and Eukarya.
Pandoravirus
Description and Significance
Pandoravirus salinus is the largest known virus to date. It is found in the sediments of Chile coastal area by Jean-Michel Claverie and Chantal Abergel, evolutionary biologists at Aix-Marseille University of France. The largest know virus on Earth is classified as Group I virus under the Baltimore Classification. The existence of Pandoravirus salinus hint the unknown parts of the tree of life and also suggest the existence of the fourth domain because only 7% of their genes match those in existing databases. http://www.nature.com/news/giant-viruses-open-pandora-s-box-1.13410
Give a brief description of the microorganism and explain why you think it is important. How does it relate to the other organisms in its phylum (bacteria and fungi) or group (archaea, virus, protist). Use the following for each reference in text (change number accordingly)--> [1]
Structure, Metabolism, and Life Cycle

When people look into cells and when they see things that don't have the right dimension or don't have regular assets or geometries, they don't think of viruses—they think its some kind of bacteria." owever, with its novel morphological features and genetic code twice the size of Megavirus, pandoraviruses will eventually add a new range of questions to the abiding question of the origins of life on Earth.

Interesting features of its structure; how it gains energy (how it replicates, if virus); what important molecules it produces (if any), does it have an interesting life cycle?
Ecology and Pathogenesis
It is reported that the virus was isolated from the mouth of Chile's Tunquen River located in central of Chile. Furthermore, another member of the Pandoravirus genus, Pandoravirus dulcius from a freshwater pond near Melbourne, Australia. Therefore, their habitat is most likely to be in water.
According to the name of the two scientist insert here, they summarized that the Pandoraviruses parasitize amoebas.
researchers say these megaviruses, which live underwater, are harmless to humans (so far) http://now.msn.com/pandoravirus-is-a-giant-virus-discovered-thats-1000-the-size-of-the-flu
Natural habitat (soil, water, commensal of humans or animals?)
If relevant, how does this organism cause disease? Human, animal, or plant hosts? Important virulence factors, as well as patient symptoms.
