Nitzschia intermedia is a pennate diatom in the family Bacillariaceae found in freshwater to slightly brackish habitats, where it inhabits both benthic and planktonic niches. Its elongate frustule with a keeled raphe and fine transapical striae is typical of the large genus Nitzschia. It serves as a bioindicator of moderate organic enrichment and nutrient levels in aquatic monitoring programs.
