Microcystis botrys is a type of cyanobacteria that typically forms colonies consisting of spherical cells clustered together like bunches of grapes. These colonies vary in size and shape, often appearing as compact, spherical or irregular masses. Each cell is relatively small, usually about 3 to 8 micrometers in diameter, and is surrounded by a mucilaginous sheath that helps maintain colony cohesion and gives it a slimy feel. Commonly found in freshwater habitats such as lakes, ponds, and slow-moving rivers, Microcystis botrys can rapidly multiply under favorable conditions, leading to the formation of blooms. While essential to aquatic ecosystems, this species can produce toxins harmful to other organisms and may pose health risks to humans during bloom events.
