Family: Nostocaceae
Genus: Nodularia
Mertens 1822

Nodularia is a genus of filamentous cyanobacteria, or blue-green algae. They occur mainly in brackish or slightly salinic waters, e.g. in the Baltic Sea. Nodularia cells occasionally form heavy algal blooms. Some strains produce a toxin called Nodularin R, which is harmful to humans. Scientific classification or biological classification is how biologists group and categorize extinct and living species of organisms. ...
