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.
Video List
Eukaryote
Aeolosoma sp.
Species name:Aeolosoma sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Aeolosoma is about 1 mm in length. There are red, yellow, or green oil droplets under the skin. The body is an elongated cylindrical shaped. Aeolosoma has a segmented body and each segment bear a pair of setae. They move like earthworm.
Eukaryote
A flagellate colony on a stalk
Species name:Anthophysis
AL-Museum AL-Museum
A colony composed of about ten flagellates is attached to a long brown stalk. The stalk doesn’t move but the two flagella on each flagellate move actively.
Eukaryote
A peanut-shaped ciliate
Species name:Amphisiella
AL-Museum AL-Museum
The shape of this ciliate reminds us of a peanut shell. We can see cirri at the front and rear ends of its slender body. To catch food, it repeats an erratic pattern of going forward, stopping, and changing directions. When it makes contact with a food particle, its flexible mouth wraps around the prey to consume it.
Eukaryote
Aspidisca sp.
Species name:Aspidisca sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Aspidisca is 25-50 μm in length. Its cell is ovoided. The back of the body is a saw tooth shape raised. There are seven cirri on the front and five on the back of the cell. They are similar to ladybird, so cirri look like small feet.
Eukaryote
A busily foraging ciliate
Species name:Amphisiella
AL-Museum AL-Museum
This ciliate is busily foraging back and forth, changing directions and passing between particles. There are cirri at the front and rear of its slender body, and the cirri at the front are especially active.
Eukaryote
A flagellate'method of locomotion
Species name:Anisonema
AL-Museum AL-Museum
In this scene of many particles and various sizes of microbes, we can see a relatively large flagellate using an interesting method to get around. It attaches its long, trailing flagellum to an anchor (like a particle or container surface) from which it launches itself forward, pulls back, and propels itself in another direction.
Eukaryote
Journey of amoeba with particles
Species name:Amoeba and Testate Amoeba
AL-Museum AL-Museum
A hidden amoeba extends several slender pseudopodia from behind the end of one particle. As the amoeba comes to other particles, it extends pseudopodia from behind the one of particle. As the amoeba never shows itself completely, we cannot recognize where it is. In the meantime the amoeba and several particles begin journey to another place together with a colony of flagellates.
Eukaryote
Encountering of two different amoebae I
Species name:Amoeba and Testate Amoeba
AL-Museum AL-Museum
Here a large amoeba is actively hunting and catching food one by one. After a while, a different amoeba appears in our field.
Eukaryote
Encountering of two different amoebae II
Species name:Amoeba and Testate Amoeba
AL-Museum AL-Museum
Two kinds of amoebae of different size and shape are coming in contact with each other, and then move away.
Eukaryote
Amphileptus sp.
Species name:Amphileptus sp.
Bureau Swerage, Tokyo Metropolitan Government
The size of Amphileptus is 100-170 μm in length. Somewhat similar to Litonotus, but bigger. Thin cilium present on both lateral surface. Longer cilia does not present in the oral region. It can be moved forward or back like Litonotus, but the movement is slow.
