1. Almost all sequenced mitochondrial genomes of ciliates and apicomplexia are linear. 2. Biology and ecology of tintinnid ciliates : models for marine plankton. 3. Secretory cells or ciliated cells are frequently found in epithelial lining. 4. Most of the soil forms are flagellates, amoebae or ciliates . 5. They hatch after six days into ciliated post-trochophore larvae. 6. Ciliated cells within the light organs selectively draw in the symbiotic bacteria.7. The biology and ecology of tintinnid ciliates : models for marine plankton. 8. In the order Pseudophyllidea, it remains enclosed in a ciliated embryophore. 9. This feature is observed in protozoan ciliates and some foraminifera. 10. The epithelia cells are ciliated , cylindrical, and teleost marine fish.
