An amoeba rights itself

This small amoeba, about 30 microns long, is lying in a flat position in the center of the screen. Numerous particles can be seen inside its transparent shell. Some pseudopods start to appear at the edges of the shell, and then suddenly the amoeba rises up on the pseudopods and slowly moves to another place.

Commentary by Prof. Yuji Tsukii, Hosei University
This video shows how an overturned Cochliopodium rights itself and begin to move again. It is a pity that we cannot clearly see the pseudopodia extending from under the shell. As this amoebae is relatively small and has a round shell, it may be Cochliopodium minus.
