Thiomargarita namibiensis are a coccus proteobacterium that are visible to the naked eye. Ooh, that's interesting! There's another type that are as well, but I can't remember their name. : (
You know what coccus means? You don't, eh? It's one of the many morphologies of bacteria. It's the spherical one.
That would make a good quiz question:
Are all bacteria micro-organisms?
NO! Hahahahahahaha! Completely insane! Deranged.
Electrons are submicroscopic (haha to those who believe [foolishly] that electrons can be seen through and electron microscope)! Hahahahehehehahahaha!
Oh, it's just a thiomargarita nambiensis.
