Epiphytic diatoms are a unique group of microorganisms that have adapted to a specialized lifestyle. They grow attached to a common stalk, which serves as an anchor on rocks or algae in various aquatic environments, including both marine and freshwater settings. This stalk allows them to thrive in shallow waters or areas with reduced clarity, such as turbid environments.One of the most striking features of these diatoms is their cell shape. They are known for their distinctively triangular or fan-shaped cells. This morphology is not only intriguing but also serves a functional purpose in their attachment to the substrate. The fan shape may provide stability and increased surface area for attachment, allowing them to resist water movement and remain firmly anchored.
