Flagellates preserved for scanning electron microscopy were
6.9 ± 0.7 μm long and 2.1 ± 0.3 μm wide, with a short anterior flagellum (6.8 ± 1.1 μm) and long posterior flagellum (14.1 ± 1.5 μm). Multi-functionality of a flagellum, for locomotion and adhesion, is relatively rare, and
previously reported from genera within the Kinetoplastea, suggesting that the flagellate on M. macrocopa may
belong to this group. To combat flagellate mass occurrence in Moina cultures, we recommend a treatment with
4 g L−1 sea salt.
