Nitzschia graciliformis is a slender, needle-shaped pennate diatom found in freshwater and brackish aquatic habitats including streams, lakes, and coastal waters worldwide. Its elongated siliceous frustule bears a distinctive raphe system along one side, enabling gliding motility. This species contributes to aquatic primary production and is used in freshwater biomonitoring due to its sensitivity to nutrient levels.

Nitzschia suchlandti is a pennate diatom in the family Bacillariaceae inhabiting freshwater environments, characterized by its narrow, elongate frustule with a sigmoid or sinuous raphe canal. Like other members of the large genus Nitzschia, it contributes to benthic and planktonic algal communities and serves as a bioindicator of water chemistry and organic pollution status.
