Eunotia serra is a distinctive freshwater diatom characterized by its curved cell outline bearing prominent tooth-like undulations along the dorsal margin. It inhabits acidic, nutrient-poor freshwater environments including bog pools, mountain streams, and oligotrophic lakes. This photosynthetic diatom is a bioindicator of acidic, oligotrophic freshwater conditions.
