Fluorescent microscope images of three ciliate protozoa from the rumen (first stomach) of cattle. The one on the left is egg-shaped and covered in waves of green, yellow and red hairlike cilia. In the center a clear, red goblet-shaped organism is topped by a bright orange shock of cilia. On the right is a green and yellow microbe that resembles an oval Koosh ball with a blue-green oval in the center. The center oval is the nucleus. These organisms have a newly discovered organelle that makes hydrogen and spurs other microbes to produce methane.
