Lithoamoebos Feldsparitroph

The lithoamoebos feldsparitroph split from its ancestor, the lithoamoeba, and moved from the Barlowe Water Table to the Ninja Sandstone Caverns. It is now a group of 2 to 4 cells, working together to feed and survive. It evolved to draw feldspars (mainly the CaAl2Si2O8 variation) from the sandstone and by chemical methods extract calcium and aluminum from it, releasing oxygen to the caverns' atmosphere in the process. It uses the calcium and aluminum to build its cell wall, but exerts small silicon molecules out of the cell wall, covering the colony with it. The Silicon is then absorbed by the lithoranjavia, which is never too far away from the lithoamoebos feldsparitroph. The lithoranjavia keeps the lithoamoebos feldsparitroph from being overrun by their own waste.
