Some species can produce toxins during algal blooms, which may be harmful to animals and degrade water quality, but not all species are toxic.

Individual filaments are microscopic, but large colonies or surface scums formed during blooms are visible as greenish, paint-like slicks on water.

Its primary importance is biological nitrogen fixation, converting atmospheric nitrogen into a form usable by plants and other organisms, enriching aquatic ecosystems.

It is a bacterium, specifically a cyanobacterium (formerly called blue-green algae). Despite its photosynthetic ability, it is prokaryotic, unlike true algae which are eukaryotic.
