A Didinium is a protist that feeds by ingesting bacteria (bacteriovorus) through a mouth-like opening at the anterior end of the cell. The cell has an equatorial gridle of cilia, with a second gridle surrounding the anterior end. Cilia may assist in sweeping bacteria toward opening.

∙ 13y agoDidinium, like all members of http://wiki.answers.com/index.php/Ciliophora, can reproduce sexually or asexually. Nucleoli degranulate before binary fission; the bands are dispersed throughout the macronucleus. These bands are segregated during division, but then re-form granular parts. The nucleoli are separated into granular and fibrillar parts during conjugation. The fibrillar parts are usually eliminated

Asexually- shrinking division. look up what shrinking division is on Google.
Sexually- it is hard to explain look it up on Google.
