Cochliopodium granulatum
Cochliopodium granulatum Penard, 1890
Diagnosis:

There is a large number of vacuoles present , all surronded by ovoid granules.

Ditch, Montfoort, the Netherlands

The brown color is the large hump of protoplasm, filled with food, on top of the amoeba and here out of focus

When the amoeba comes into the light beam of the microscope, it discharges its digested food particles within some minutes. This typical phenomenon can also be observed in other Cochliopodium species.
