Yokto Crystal

The yokto crystal split from their ancestor, the marine crystal. They have moved up to the Yokto waterways thanks to the nitrogen microbes. Like their ancestor, they are made of a hard photosynthetic chitin which has tiny holes in them, these holes let in water and organic matter. Inside the red fungi-like interior consumes the organic matter. This same fungi-like material also makes up the "roots" of the shallows crystal and it can absorb needed nutrients and minerals from the soil. The same holes that let in food also let out tiny spores which float into the water and grow into new yokto crystals. It has retained it's ancestor's mild poison which is used to deter any herbivores who are not immune against it from eating it.
