Nitzschia bergii is a freshwater diatom in the family Bacillariaceae, distinguished by its elongated, narrow valve with a distinctive marginal keel. It is found in benthic communities of rivers and lakes, often associated with slightly enriched conditions.

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.
