Is the flu virus breathing? Is the coral polyp breathing?

A virus is a special kind of living organisms. They carry genetic information, they have the characteristics of living organisms, but gas exchange is not typical for most viruses, including the influenza virus. The coral polyp is an interesting organism. There is no direct gas exchange, since they are in the water. But he still gets the right amount of oxygen and other dissolved gases through water filtration. Also, with the help of filtration, coral polyps feed by capturing microorganisms. For a day, they are able to pass a huge amount of water through themselves.
