The barlowe ciliognathus split from its ancestor, the ciliognathus. It has gotten larger and has specialized as a "micro herbivore". It eats only producer microbes like heplumnia. It has developed a thicker cytoskeleton to help it retain moisture. It can now travel on land, however its limited to muddy soil. It has also developed an antifreeze-like chemical to keep it from freezing in the cold polar soil and water.
Like its ancestor it normally 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 barlowe ciliognathus and they fuse together. They then exchange genetic material. The two detach and then become four new cells.
