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 taking turns
Species name:Frontonia
AL-Museum AL-Museum
A large, dark, oval ciliate is busily foraging around particles. Soon another type of ciliate with a slender shape joins in the foraging. Eventually the first one leaves to search for food elswhere.

Darting and dashing
Species name:Frontonia (Frontonia leucas)
AL-Museum AL-Museum
A large ciliate whose whole surface is densely covered with cilia is darting around. It pauses for an instant and then dashes into a group of particles. This violent activity disturbs the peaceful habitat occupied by small algae and flagellates.

Swimming movement of Favella ehrenbergi
Species name:Favella ehrenbergi
Graduate School of Life Science, University of Hyogo Taniguchi Atsushi
Favella ehrenbergi is a marine ciliate that has a transparent shell shaped like a wineglass and swims in water by using cilia projecting from the mouth of the shell. They contract and retract their body in the shell by receiving a stimulus, but after a time they extend their body and start to swim again.

Bacterium moves like a tank 2
Species name:Flavobacterium johnsoniae
Gakushuin University Daisuke Nakane
Flavobacterium johnsoniae and many other members of Bacteroidetes exhibit rapid gliding motility over surfaces by a unique mechanism. These cells do not have flagella or pili; instead, they rely on a novel motility apparatus. SprB, a 669 kDa cell-surface adhesin, is required for efficient gliding. Here, we showed dynamic movements of SprB were observed by fluorescent microscopy. SprB moved at a constant speed of 2 um/s on the cell surface along a left-handed helical closed loop, appears that the cell have a moving conveyer belt. Attachment of SprB to the substratum was associated with cell movement, suggesting a model for gliding, in which adhesins are propelled along a helical track, generating rotation and translation of the cell.
