Navicula bifrons is a diatom species characterized by elongated and linear valves with rounded ends. These valves typically range from 10 to 100 micrometers in length and feature a narrow central area and a linear axial area. The surface of the valve is marked by fine pores called areolae arranged in linear rows. A slit-like structure known as the raphe runs along the valve’s length, aiding in movement and attachment. Navicula bifrons is widespread in aquatic environments, contributing to primary production and nutrient cycling within ecosystems.
