Baatsalia

Baatsalia is a domain of life from the planet Baatsal in the Gigyanshi system, sector T54-Y21-Z41

It is silicon-based life in a sulfuric acid world, and for a time its status of being alive at all was disputed.

The lifeforms create communal colonies of silicon-compound slabs that resemble rock; however the slabs are relatively low-density, porous, and elastic. They float and grow on sulfuric acid seas, eventually outgrowing their structural integrity, at which point they begin to tear and fracture.

Due to their porous nature and sources of food, sections of the lifeform colonies slowly increase in density over time, eventually accumulating enough material that their density surpasses that of the acid sea. At this point the dense section will be separated from any larger colony it is a part of, after which it sinks and dissolves, adding its constituent resources back into the environment.
