Filamentous cyanobacteria of the genus Lyngbya are important contributors to coral reef ecosystems, occasionally forming dominant cover and impacting the health of many other co-occurring organisms. Filamentous cyanobacteria that differentiate multiple cell types are considered the peak of prokaryotic complexity and their evolution has been studied in the context of multicellularity origins.

Some filamentous blue-green algae have It is also significant that certain unicellular Cyanobacteria became the first chloroplasts in algae. Cyanobacteria and algae are also symbionts with fungi in lichens .

They are not algae, though they were once called blue-green algae. It is a phylum of bacteria, with about 1500 species. In endosymbiont theory, chloroplasts (plastids) are descended from cyanobacteria. Recently, 37 genomes of unicellular and filamentous cyanobacteria have been available, which facilitate cyanobacterial systemic analysis for metacaspases family Medical Definition of Cyanobacteria. 1.
