Scanning electron microscope photograph of the ciliate Tiarina with its 100-150 micrometer calcium carbonate (calcareous) shell containing the Symbiodinium cells (not visible here)

Confocal microscope image showing the inside of the ciliate Tiarina, containing between 10 and 20 cells of the microalga Symbiodinium. They are visible with their red chloroplasts and blue nuclei. The ciliate Tiarina (the host) whose nucleus is visible in light blue, has cilia on its surface, which enables it to swim. Scale bar: 20 micrometers.
1One micrometer is 10-6 m, or 0.000 001 meters.
