Sea Rupee

Split off from the Binucleus Crystal Shrub, the sea rupee grows anywhere it can on the seafloor like a strange sharp crystalline grass. It has simplified to one crystal per individual, making it more difficult for parts to break off from water currents. It absorbs sunlight and takes in minerals and dead organisms with its roots for energy and nutrition. It is otherwise very similar to its ancestor; it is made up of a fungus covered by a mineral and chitin photosynthetic layer, it comes in many colors dependent on how much light it has access to (with those with the most light being green), and it reproduces sexually with water-borne spores.
