Neaquaductus sarcina
As Aquaductus networkus grew and spread some fragments reach zone 17 along with Gigantocytus rhizoma. They began to adapt to the change in salinity at the river delta. Over time they managed to live in Zone 17 by store more salts in G. rhizoma. This led to A. sarcina.
A. sarcina grows similarly A. networkus except now it mostly reproduces by fragmentation in conjunction with its symbiote, now Gigantocytus taisa. In addition to using G. taisa for storage it uses it to facilitate its reproduction. When G. taisa is ready to reproduce it sends inhibitor proteins into A. sarcina that cause new cells that are formed to be closed at the end. G. taisa will fill these cells with zoospores. Once the zoospores enter the cell it will close off the other end and break off from the rest if the A. sarcina colony. It will drift away until it reaches a bed of dead Micralgearous greana. It will open both sides, releasing the packaged zoospores and it will began to break down the dead M. greana and grow more cells until it attaches to the G. taisa that it delivered. This relationship ensures that A. sarcina can reliable have G. taisa and vice versa to rely on.
A. sarcina typically grows a more branching network to allow for more nutrients to be obtained. A. sarcina relies heavily on G. taisa for salts and nutrient storage. It can still reproduce sexually when nutrients in an area get low. It will produce many package cells that it fills with gametes and zoospores from G. taisa and then they will fragment.
