Euglena sanguinea
Ehrenberg 1830
Syns: E. viridis var. sanguinea F. Stein, E. haematodes (Ehrenberg 1830) Lemmermann 1913

Euglena sanguinea Species: 80-170 μm long, 25-45 μm wide; posterior bluntly rounded; flagellum about the body length; pellicle striated; chloroplasts elongated, parallel to the striae; haematochrome granules scattered in sun light and gathered in central area in darkness (Kudo, 1966).
