Video archives
Here, we establish an online video library where a series of movies relevant to motility are available. The miscellaneous category includes bacteria, eukaryotes, and archaea, viruses, proteins, and synthetic polymers. The movies that are meaningful in the biology field will be uploaded in both Japanese and English.
For the contributors who plan to upload your video, you should keep in mind the following suggestions:
(1) the video which is relative to the object of your research
(2) the video about microbe found in the research activity of the super-science high school or biological clubs are encouraged to upload
(3) Do not forget to add the link of your video which has been published (Please make sure the copyright)
(4) If you think some videos in the old textbook are valuable to upload, please let us know.

Eukaryote
Philodina sp.
Species name:Philodina sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Philodina is 300-1,000 μm in length. The body is thin long. One foot with four toes. The head has two crown of chilia. The eyespots lie on the brain. It moves like leeches. It shows leech-like movement and moves around flocs. Philodina feed on algae and bacteria. It can retract cron of cilia into the body.

Motility of Paenibacillus sp. NAIST15-1 (1)
Species name:Paenibacillus sp.
Graduate School of Biological Sciences, Nara Institute of Science & Technology Kazuo Kobayashi
Small moving clusters of wild-type strain cells on a 1.5% agar plate. The wild-type strain was spotted on a 1.5% agar plate and incubated at 37°C for 6 h. Coverslips were placed directly onto the surface of the leading edge zones of the colonies and cell morphology observed under a video light microscope. The movie is real time. Scale bar, 20 μm.

Motility of Paenibacillus sp. NAIST15-1 (3)
Species name:Paenibacillus sp.
Graduate School of Biological Sciences, Nara Institute of Science & Technology Kazuo Kobayashi
Time-lapse analysis of colony formation. One microliter of Paenibacillus sp. suspension was spotted onto a 1.5% agar plate, which was then incubated at 37°C. The process of colony formation was analyzed by time-lapse light microscopy. Time-lapse images were collected every 1 min for 16 h after inoculation. Playback speed, ×1,440. Scale bar, 2 mm.

Motility of Paenibacillus sp. NAIST15-1 (4)
Species name:Paenibacillus sp.
Graduate School of Biological Sciences, Nara Institute of Science & Technology Kazuo Kobayashi
The cmoA mutant retains functional flagella. cmoA mutant cells were spread over the surface of a 1.5% agar plate and incubated at 37°C for 5 h. Two hundred microliters of water were poured onto the colonies and cellular behavior was immediately observed under a video light microscope. The movie is real time. Scale bar, 20 μm.

Species name:Paenibacillus sp.
Graduate School of Biological Sciences, Nara Institute of Science & Technology Kazuo Kobayashi
Cellular behavior of the wild-type strain at the leading edge zones of swarming colonies on 0.6% agar plates. The wild-type strain was spotted onto the center of 0.6% agar plates and incubated at 37°C for 6 h. Coverslips were placed directly on the surface of the leading edge zones of the colonies and cell morphology observed under a video light microscope. These movie is real time. Scale bar, 20 μm.

Motility of Paenibacillus sp. NAIST15-1 (7)
Species name:Paenibacillus sp.
Graduate School of Biological Sciences, Nara Institute of Science & Technology Kazuo Kobayashi
Wandering colonies are sensitive to wetness. Wild-type cells were spread over the surface of a 1.5% agar plate and incubated at 37°C until wandering colonies appeared. Two hundred microliters of water were poured onto the colonies and cellular behavior was immediately observed under a video light microscope. The movie is real time. Scale bar, 20 μm.

Struggle to get free
Species name:Phacus and Pandorina
AL-Museum AL-Museum
This flagellate is characterized by a teardrop shape, a short flagellum in front, and its rear end tapering off to a point. It usually moves by fluttering its body, but here it is caught on a particle and desperately writhes to get free.

Spinning and resting
Species name:Pleuronema
AL-Museum AL-Museum
A ciliate of light green color and flat oval shape is resting. Its long cilia are extended in all directions. After a while, as if suddenly awakened, it spins vigorously and shoots out of our field of view.
