One notable addition, Mamavirus, which is actually considered to be even larger than Mimivirus, has led to the startling discovery of a large virophage. Yes, even viruses have their own parasites that are detrimental to their own reproductive success. A satellite virus, named Sputnik, was found in Mama's cytoplasm by La Scola et al. in 2008, and this finding has brought up questions regarding whether or not viruses can be alive; can non-living organisms be parasitized? Virologist Jean-Michel Claverie says, vehemently, "There's no doubt this is a living organism," and he and Eugene Koonin suggest that the further blurring of divisions between 'living' and 'nonliving' that comes with these new discoveries means the 'imaginary line' between viruses and cellular organisms should be erased. There still are a lot of viruses out there (esp. in the ocean) than can change our thinking about the organism as a whole.
