Nitzschia angularis is an elongated, pennate freshwater diatom with angular poles and a distinctive raphe positioned along the keel of the frustule. It inhabits eutrophic to mesotrophic freshwater environments including rivers, ponds, and nutrient-enriched lakes. This photosynthetic diatom is associated with moderately enriched freshwater conditions.

Nitzschia modesta is a small pennate diatom in the family Bacillariaceae, inhabiting freshwater to slightly brackish environments. Its elongate frustule with a sigmoid raphe is characteristic of the large and ecologically diverse genus Nitzschia. As a benthic or epiphytic microalga, it contributes to biofilm communities on submerged surfaces.
