I found this amoeboid several times in a freshwater pond (Crailoo, the Netherlands). The cell is small, about 10 µm in diameter, with 3-6 granulopodia, extending from one side of the cell, thus resembling a comet. The granulopodia are retractive. When disturbed by a passing protist, they can retract extremely fast, just like some helizoans do. After a short time, the granulopodia stretch again. All observed specimens (n=4) were surrounded by debris.
