I was fortunate enough to capture this giant ciliate from a freshwater lake at Assam. This heterotrophic ciliates is also called trumpet animalcules. The name is given due to the horn-shaped/trumpet structure. They are also among the biggest known unicellular organisms. It has a ring of prominent cilia around the anterior by which they sweep all the foods coming in their way to its tummy. This way they changes their shapes too. Cheers,
