From: Morphostasis in a novel eukaryote illuminates the evolutionary transition from phagotrophy to phototrophy: description of Rapaza viridis n. gen. et sp. (Euglenozoa, Euglenida)

Figure 2

Scanning electron micrographs (SEM) of Rapaza viridis n. gen. et sp. A. SEM showing a relaxed elongated cell with helical pellicle strips and two flagella. The anterior flagellum (AF) and the posterior flagellum (PF) insert into the anterior part of the cell. B. SEM showing an R. viridis cell that has bored a hole into the cell surface of a captured Tetraselmis cell (arrowhead). The internal contents of the captured Tetraselmis cell (arrow) are being withdrawn by myzocytosis. C. SEM showing R. viridis engulfing a Tetraselmis cell (arrowhead). D. SEM of R. viridis showing posterior strip reduction (*), which connected by lines, forms a square-shaped whorl. Scale bars 5 μm in A-C; 2 μm in D.
