English: The picture was taken on a digital microscope levenhuk. Making cilia undulating movements, the Paramecium ("Slipper animalcule") moves (floats blunt end forward). The cilium moves in a single plane and makes direct (efficient) shot in the straightened condition, and return — bent. Each of the next cilium in the series does punch with a slight delay compared to the previous. Floating in the water column, the Paramecium rotates around the longitudinal axis. Speed — about 2 mm/s. The direction of movement may change due to the bending of the body. When confronted with an obstacle, the direction of a direct strike is reversed, and the Shoe bounces back. Then she for some time, "swinging" back and forth, and then again begins to move forward. Ciliates on the body has a recess — cellular mouth that enters the cell throat. Around the mouth are specialized cilia of the circumoral ciliatory, "glued" in complex structures. They are forced down your throat along with the stream of water is the main food of the ciliate — bacteria. Ciliate finds its prey, feeling the presence of chemical substances that produce an accumulation of bacteria.
