Scale bar indicates 50 µm.

Fig. 2: Nuclearia simplex after binary fission with a thin plasma thread that still connects the two cells. The upper cell caught a cryptophyt flagellate of the species Goniomonas truncata.
Scale bar indicates 25 µm.

blue (pseudopodia), orange (mitochondria), brown (contractile vacuole), green (nutrition vacuole),
black (nucleus).
