Clustercytus

The clustercytus split from its ancestor the bimarincytus. It has spread across the surface of the Sagan 4's oceans and coastlines. Rather than a single cell it grows in radial clusters. On the end of each flagellum grow more photosynthetic cells. They grow in large numbers where nutrients are brought up from the deep oceans or near river deltas. During most in the autumn when conditions are right and create large "blooms" which tint the water a green hue. While they cannot move on their own they are spread through the vast network of sea currents. They still reproduce via binary fission.
