Hello,
Dinobryon is commonly known as a formation of several cells, fighting together through the water-drop. Here I want show a species, Dinobryon utriculus, that is found as single cells, attached to a substrate like filamentous algae, e. g. a zygnema:
With phase contrast you can see the stem with which D. utriculus is attached to the Zygnema and also the typical two falgella, one short and a long one.
I think it is remarkable, that D. utricukus with its stem is even able to overcome the mucous layer that surrounds Zygnema.
There is also a small video (~400kb, divx-coded) available. It shows the movement of the two flagella:
