I watched this small green flagellate approach and move up against the surface of this amoeba. Big mistake. The amoeba slowly extended a welcoming pseudopod around the little fella, and next thing you know it's a food vacuole!
It has been said that amoeba are attracted by movements of the intended prey or by substances emitting or diffusing from it. They also tend to avoid things that show intense activity. Proably because the amoebae are so slow in their movements. In other words, the amoebae must be pretty healthy since they do not consume fast food.
