Ciliognathus

Ciliognathus is a cilliated organism that has an oral grove shaped like horizontal jaws, which helps it consume smaller cells. It also has the option to filter edible particles.

It reproduces by binary fission, but in certain conditions, like overcrowding and environmental stress, it undergoes a sexually reproductive process called conjugation. It lines up with another Ciliognathus, and fuses together. It then exchanges genetic material. The two ciliognathus detach. The two become four new cells. Paramecia reproduce this way for the same reasons.
