Coscinodiscaceae is a family of diatom the order Coscinodiscales. Diatoms are a type of algae characterized by their unique silica cell walls.
The family includes several genera, such as Brightwellia, Coscinodiscus, Craspedodiscus, Palmeria, and Stellarima. [1]
Members of the Coscinodiscaceae family typically exhibit disc-shaped, cylindrical, or wedge-shaped cells. Their frustules (silica cell walls) can be quite large, reaching up to 500 µm in diameter. The valve face is flat or lens-shaped, with radiate areolae extending from a central annulus.
Species within the Coscinodiscaceae family are widely distributed across various aquatic environments, ranging from oceans to freshwater bodies. They are found in regions from warm waters to boreal zones. [2]
Diatoms, including those in the Coscinodiscaceae family, play a crucial role in aquatic ecosystems. As primary producers, they generate organic matter through photosynthesis, which supports the food web. [2]
