Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. Brown algae is NOT dangerous to the fish, so don't kill them trying to get rid of it. Like the chrysophytes brown algae derive their color from the presence, in the cell chloroplasts, of several brownish carotenoid pigments, as fucoxathin. Algae belongs to four different kingdoms, including the kingdom bacteria, kingdom plantae, kingdom protista and kingdom chromista. However, they belong to their own kingdom of life - Chromista or the brown algae. They are commonly known as Kalps. Of the estimated 1,836 species in approximately 285 genera, fewer than 1% are found in freshwater habitats.
