A strange-shaped Euglena

A dark green Euglena is moving very slowly. The body is longer and seemingly less flexible compared to other types of Euglena. It twists its body but does not expand and contract. This type has a striped pattern on its surface.


Commentary by Prof. Yuji Tsukii, Hosei University
This organism is Euglena spirogyra, which is often found in wet media such as marsh, swamp and paddy.
