INFUSORIAN PREDATORS

Among the ciliates there are predators that are VERY picky in relation to their wife, here it is advisable to use didinium ciliates (Didinium nasu tum). Didinium is a relatively small ciliate, averaging about 0.1–0.15 mm long. The front end is elongated in the form of a proboscis, at the end of which the mouth opening is placed. The ciliary apparatus is represented by two corollas of cilia. Didinius swims quickly in the water, often changing direction. The preferred food of the didinia is shoe ciliates. In the preliminary case, the predator is smaller than its prey. Didinium develops into a prey with a trunk, and then gradually the mouth opening expands more and more, swallowing the shoe of the infection!
