FIGURE 2. Mallomonas divida. A–D, collar scales with different shield patterns. The dome is partly reticulated by circular meshes; A–C, scales viewed in a transmission electron microscope (TEM); D, a scale viewed in a scanning electron microscope (SEM). The pattern on the shield is formed by one or several rows of more distinctive papillae; E–H, body scales with different shield patterns; E–G, scales viewed in TEM; H, a scale viewed in SEM; I, a rear scale with one anterior flange considerably longer than the other; J, two rearmost scales possessing spines; K, the scales comprising the scale case. Bar = 0.5 µm, if not stated otherwise. A–J are shown at the same magnification.
