Chlamydodon mnemosyne, a brackish-water ciliate which feeds on cyanobacteria, is capable of sensing the direction of light. Cells are negatively phototactic in the well-fed state and tend to swim towards the light source when mildly starved. Severely

The cyrtophorid ciliate Chlamydodon mnemosyne shows accurate orientation with respect to the direction of light. Positive phototaxis occurs during mild starvation, while the cells are negatively phototactic in the well-fed state. Beside the determination

Three new cyrtophorian ciliates isolated from coastal areas of China were described based on morphological and genetic data. The Chlamydodon mnemosyne-like species Chlamydodon similis sp. n. differs from its congeners mainly by its number of somatic kineties.

Fabrea salina is a marine ciliate that shows both step-down photophobic reactions and positive phototaxis. To determine the nature of the phototaxis photoreceptor pigment we have measured the action spectrum of phototaxis of this ciliate by means of an

This study investigates the morphology and molecular characteristics of three new cyrtophorid ciliates isolated from China seas: Chlamydodon salinus n. sp., Chlamydodon caudatus n. sp., and Chlamydodon paramnemosyne n. sp. Of these, C. salinus n. sp.
