Extreme phagocytosis. H.S. Jennings’ account (Jennings, 1976) of observations by Rhumbler in 1898: “Ameba verrucosa coiling up and ingesting a filament of Oscillaria. The animal settles upon the middle of an Oscillaria filament, envelopes it, and lengthens out along it (a). Then one end bends over (b), so that a loop is formed in the filament (c). The amoeba then stretches out on the filament again, bends it over anew, and the process is repeated until the filament forms a close coil within the amoeba (c to g).”
