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.
