Stephanopogon apogon (steff-anne-owe-poe-gone) is a marine genus of uncertain affinities and include a small handful of species. Cells are dorso-ventrally flattened, with a wide anterior mouth which may or may not have some barbs. It moves by using flagella which are laid out in longitudinal rows. This organism was for a long time through to be a ciliate - because it looks like a ciliate. But examination of the cellular organization revealed that it s internal architecture was very different to that of ciliates - and they don t have two kinds of nuclei - like ciliates. Like many ciliates, it has flagella in rows or kineties. The anterior margin is the mouth, and the eat bacteria. Differential interference contrast.
