Dire Tess

From 2speccers2tools wiki

The Glass block is a rather unspecialized multicellular organism, as it's easily able to reproduce via fragmentation and that it lacks differentiated interdependent tissues. It would seem logical then that a split would assume an even less cohesive form: enter the Dire Tess, a genus of grex-forming planktonic silicate algae.

Species of Dire Tess can be easily distinguished from one another as single units due to the forms of their silicate shells, allowing them to take on well-defined polygonal shapes. In conditions where nutrients are abundant, these units congregate and link up, forming more elaborate composite shapes; colonies can also form from a single unit cloning itself profusely. Not only does this colony-forming behavior ensure that nutrients and materials are shared, but this can also protect them from predators to a degree - dealing considerable damage to the oral linings of certain multicellular organisms. By forming colonies, genes can also be exchanged between units, allowing for the production of genetically distinct offspring. When nutrient availability has reached enough of a lull (e.g. dissolved silica), all units sever their connections from one another and resume life as individual cells.

Unique to all glassflora, Dire Tess can manufacture sugars via a photosynthetic compound known as invisibilin.
