Cruxir

the cruxir split from their ancestors, often living relatively close to their ancestors. The cruxir population is larger than the cruris population, however. The cruxir nucleus's flagellum have developed into a 'cord' that serves to further connect the 'daughter' cells to the main cell. It can 'launch' the daughter cells away from it but still be connected by the cord. This allows them to cover a greater area and get more sunlight. The cruxir not only uses purple light, but also a range of red light as well. The cruxir's movement pattern hasn't changed significantly, although it is capable of quick "spinning" motions using it's extended daughter cells to spin. This can confuse and/or scare possible predators. Large groups of cruxir and cruris can create a thin lime-green film on the surface of the water, while when below the surface it appears as if the water is a murky light green.
