Trithigmostoma cucullulus Mueller, 1786
Tritighmostoma cucullulus; a cyrtophorid ciliate trying to ingest a diatom (but failed), specimen from (3)
Tritighmostoma cucullulus; specimen from with ingested diatoms (2)
Tritighmostoma cucullulus; same specimen, focus plane on the dorsal brush and pattern of the alveoles in the cortex. (2)
Tritighmostoma cucullulus; crop of the above image: dorsal brush. (2)
Tritighmostoma cucullulus; juxtaposition of two images of the anteror part of the same specimen. Upper image: focus plane on the basal bodies of the cilia and the pattern of the alveole. Lower image: focus plane on some rows of circular structures which may be mitochondria. Alos conspicuous is the different optical appearance of the oral basket, which is birefringent and therefore is light or dark dependent from the orientation relative to the polarizing light of the differential interference contrast (DIC) of the microscope.
Tritighmostoma cucullulus; another specimen from (2), dividing stage. The yellow arrows point to the two oral baskets (one for each future individuals). The green arrow points to the one of the adoral membranelles. (1)
Tritighmostoma cucullulus; Crop of the above image. The green arrows point to the exits of the contractile vacuole. The vellow arrow points to the adoral membranelle. (1)
Tritighmostoma cucullulus; another specimen; focus plane on the macronucleus (Ma) and the dorsal brush (DB) (1)
Tritighmostoma cucullulus; another specimen, trying to swallow a diatom (3)
