This is probably the most abundant very small (3-5 um diameter) single-celled species in the lake, at times reaching 3000-5000 cells/ml. Erkenia can occur in the water at all times of the year although it tends to be more abundant in winter. In addition to the small cell size and shape of the chloroplasts, two flagella are characteristic of this species. Unfortunately the flagella are not seen in the specimens presented in this photograph.
