What is the complexity of the structure of ciliates-shoes in comparison with other protozoa?

The ciliates have shoes: 1. A prototype of the digestive system, including the mouth-> pharynx-> digestive vauol-> powder (excretion of undigested residues), therefore, digestion is faster. 2. Excretion is carried out through 2 contractile vacuoles with the adducting tubules, therefore, the excretion is faster. 3. Has 2 nuclei: • large – macronucleos, for the regulation of metabolism and asexual reproduction. • small – micronucleos, for sexual reproduction.
