Trichoplax adhaerens F. E. Schulze is a flat, allround flagellated organism, with its systematic position at the basis of Metazoa. The film shows its modes of movement, the activity of its flagella, and views of the dorsal and ventral surface. Within the intermediate layer, the contractions of the fibrous cells are recognizable. During the extracellular digestion of prey organisms (cells of Cryptomonas), Trichoplax adhaerens carries out characteristic "smearing movements". In elevations of the animals ("digestive sacs") prey organisms can be intaken, its indigestible leftovers remaining behind.
