<unk> es are oval in shape and are about 1 micrometer (1000 nanometers) in length. Other viruses range from 25 to 100 nanometers. In addition to being large physically,<unk> es have a large genome made up of 2,500 genes, compared to only 10 genes on average in other viruses. For example, the Influenza A virus contains 7 genes and HIV contains only 9 genes. Gene content varies among species of<unk> , with<unk>  salinus, containing 2,500 genes and<unk>  dulcis containing about 1,500 genes.<unk> es were originally mistaken for bacteria, however, they are missing some of the distinct features of bacteria such as the ability to make their own proteins. The dissimilarity of the remaining genes to any cellular genes led researchers to speculate that this virus may represent a previously unknown branch of the tree of life. However, experts not involved in the study have called that suggestion premature because there is very little evidence supporting the idea. They are also seemingly capable of moving on their own, unlike other viruses.
