Cross-sections of tentacles revealed rings (cylinders) of 14 microtubules with spokes. The number of microtubules per ring decreased from 14 to 12 or 11 inside the cell but no true kinetosomes were detected. These "micro-rings" were often associated with extrusomes and the tentacle tips consisted of extrusomes. A nucleus of a symbiotic alga was present, surrounded by algal cytoplasm containing plastids and delimited from the ciliate cytoplasm by two membranes. Each plastid was bounded by four membranes and was associated with one nucleomorph, suggesting a symbiotic origin as a cryptophyte.
