An amoeba with an unusual shape

An amoeba about 70 microns in diameter is sitting still. It extends pseudopodia in all directions, but unlike the stiff axopods of Heliozoa, these pseudopodia are soft and thicker at the base. We can see numerous food particles inside the body.


Commentary by Prof. Yuji Tsukii, Hosei University
This organism is a testate filose amoeba called Gromia. In this video, only the shell is in focus. If the organism were completely in focus, we could probably observe its long, thin filopodia.
