Further details:
Flagellated algae and protozoa

Name (genus): Euglena

Size : 25 - 100 µm

Where to find them : Planktonic, often colouring the water green.

Notes : Euglena, like some other micro-organisms, have features of both algae (e.g. green and photosynthesise) and protozoa (moves with whip-like flagella). Thus biologists debate how they should be classified. It also has a red eye spot.

You may come across them when viewing a larger organism under the microscope. Euglena, if abundant, may cross the field of view moving in and out of focus.

Classification :
Kingdom - Protoctista, Phylum - Discomitochondria (apparently a new interim phylum. See
