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
Chaetonotus sp.
Species name:Chaetonotus sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Chaetonotus is about 220 μm in length. The body is ovoided. The tail dives into two. They are covered with cilia and the head’s cilia is very long. They glide fast. The food source are dead bodies of micro-organisms and filamentous alga.

Cephalodella sp.
Species name:Cephalodella sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Stentor is 120-180 μm in length.

Eukaryote
Chaetospira sp.
Species name:Chaetospira sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Chaetospira is 25-50 μm in length. The body is enveloped in a flask-like lorica attached to the flocs. They have the bristles in the front end of the body with three cirri rows. Their end of the body is elongated. The food source are Diatoms or smallMastigomycetes.

Eukaryote
A round green flagellate
Species name:Carteria or Chlamydomonas
AL-Museum AL-Museum
A round green flagellate glides along and then stops to rest on the surface of an aggregate. Numerous fine green particles are contained inside the flagellate. After a while, the flagellate leaves the particle, giving us a brief glimpse of its long flagellum.

Eukaryote
A small ciliate moving delicately
Species name:Cinetochilum margaritaceum
AL-Museum AL-Museum
A small ciliate about 30μin length is busily moving here and there. Its cilia are unusually long and thin compared to its body size, which makes its movements appear delicate.

Eukaryote
Algal cells among particles
Species name:Closterium
AL-Museum AL-Museum
A long colony of green algal cells is rigidly connected, resembling a pole. It moves in a straight line, either forward or backward, toward a particle. Another type of individual green algal cell is half-hidden behind the particle. A Euglena cell is attached to the particle and does not move. There are numerous unmoving diatoms surrounding the particles.

Eukaryote
A Chilodonella ciliate
Species name:Chilodonella
AL-Museum AL-Museum
The front of this ciliate, Chilodonella, is slightly bent and flexibly changes shape when it touches an obstacle. The shape of its body resembles a kidney bean, but we cannot recognize its characteristics in detail because the organism keeps disappearing behind particles.

Eukaryote
A leisurely green alga
Species name:Closterium
AL-Museum AL-Museum
A large algal cell more than 600 microns long is moving slowly. Both ends of its straight body are slightly tapered. We can see green particles inside the cell.

Eukaryote
A strange-shaped ciliate
Species name:Campanella or Vorticella
AL-Museum AL-Museum
The shape of this ciliate, Stokesia, reminds us of a ski cap or a bag. Although it stands perfectly still, the cilia surrounding its broad mouth are vigorously moving in an effort to stuck small food particles into the body.

Eukaryote
Flagellum stuck to a particle
Species name:Chlamydomonas
AL-Museum AL-Museum
A round green flagellate cannot move because one of its two flagella is stuck to a particle. Soon it breaks free and swim away.
