These are some pretty neat photographs here Gerd. Very Happy The long cirri of the Stichotricha causes it to remind me of a centipede. Wonder how they go about building their tubes. Think

Thanks, Ken, Doug and Wim. I never could observe them building their housings until now.
Normally it takes 3 to 5 hours to let them finish the jelly housings. That is the time i normally wait
after taking the samples and putting the cover slides onto the water surface.
Wim, do you know the Internationale Mikroskopiertage in Hagen ?
Did you ever visit this meeting of microscopists here in Germany ?
You will find more informations here : http://www.mikroskopie-hagen.de/html/tagungsprogramm.htm

If you put a cover slip on teh surface of the water of a sample for a day you can find many organisms that build mucus tubes, even bdelloid rotifers.

I've never been to one of the microscopiertagen. My german is not very good. Although german is more similar to dutch my english is better.

I think some of my microscopy club members go to german microscopy meetings. Perhaps I should too.

best regards,

Wim

Thank you Gerd for posting these fine images with the subject identified. I have captured some images of this subject in brightfield but didn't know the name of what I had recorded. My subject had formed it's tube in a mass of debries and I never could see it directly. Does it travel with the tube once formed? The one I photographed had a beautiful fan along about 1/2 of it's body lenght. This is partially seen in your center image. When I have some time I may post an image.
