As Retus duoformus persisted in Zone 27, it would miss some nutrients due to the openings in its net. Overtime some members began growing more net cells, this led to Retus sollus.

R. sollus is overall very similar to R. duoformus except the net is is filled with net cells, leaving no openings. Because of the increased demands for nutrients from the more intensive growth, R. sollus grows about 1/3 as fast as R. duoformus. The cells divide at a rate of once every 40 minutes. Even though it grows slower, it can grow larger due to the greater consistency in nutrient intake reaching a diameter of 400μm. The ring cells are 20μm long and 8μm wide, and the net cells are 20μm long and 5μm wide.. They still get nutrients from Nebulimpa protos and detritus.

The cells have their genetic material contained within a nucleus, lysosomes for breaking down food matter, and vesicles for the movement of food within and between cells. Reproduction occurs when a ring cell splits and a new ring cell is formed that sits outside of the old ring while remaining attached. The new cell will be fed from the parent net and will begin to develop its own ring and net once it the new ring reaches a diameter of 100μm it will split off and continue to grow.
