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.

Two ciliates: big and small
Species name:Balladyna, Remanella
AL-Museum AL-Museum
A small ciliate with cirri at the front and the rear is foraging among particles. Then a giant ciliate about four times larger appears, but it soon turns and swims away.

Blepharisma sp.
Species name:Blepharisma sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Epistylis is 150-400 μm in length and 20-50 μm in wide. Some speices size are more than 3 millimetres. The body is a long cylinder-shaped and its color is yellow or brown. The peristome is occupying about 1/3 body length from front end of the body. It have myoneme in the body. They move with gliding, and sometimes swim with shrinking spiral.

Dancing Bacillaria
Species name:Bacillaria
AL-Museum AL-Museum
Many cells of Diatom are connected side by side and each cell is gliding back and forth. As a whole, it looks like a dancing bamboo blind.

Mysterious behavior of Bacillaria
Species name:Bacillaria paxillifer
AL-Museum AL-Museum
Bacillaria is a colony in which numerous individual diatoms are connected. The individual diatoms are lined up side by side, which looks like a window blind when the colony is contracted. When the colony stretches out, the diatoms are connected nearly end to end in a long chain-like structure. Bacillaria usually moves in a straight line when extended, but can change directions freely when contracted. Various small diatoms, aggregates and crystals are stuck to Bacillaria and move along with it.

The gliding motion of diatom, Bacillaria paradoxa Part 1
Species name:Bacillaria paradoxa
Graduate School of Life Science, University of Hyogo Nozomi YAMAOKA
Bacillaria paradoxa belongs to pinnate diatom and forms a colony consisting of 2-30 cells, like a raft. Adjacent cells show active sliding each other. This gliding mechanism and physiological meanings are not understood. This motion looks like “Nankin Tamasudare”, a street performance using bamboo screens.
