( Update)

I posted some movies of some Arcellas that I observed, going for rides inside a (possible Frontonia?) and one clip inside a Flatworm.

OK, I need some help here. I watched the videos, and that sure looks like an Arcella test running around inside a Paramecium, but how did the test get INTO the Paramecium!? :shock: I always thought the gullet of a Paramecium was a skinny little tube that excluded anything very big. :?

Hi Thomas,
very nice Videos!! Are you dead sure about the Ciliate being a Paramecium? It looks a bit like Frontonia which would also explain the capability of swallowing large chunks!

Some pretty good videos Thomas :D . I was going to comment on the fact that it may not be a Paramecium but Bernhard beat me to it. :lol: What ever kind of ciliate it may be, it definitly looks as though it has had Arcella for a meal. I am not familar with Frontonia so I cannot comment on the organism. The videos like I said were good but a little on the hot side making it hard to determine what type of ciliate it really is, other than going by the shape of the cell. Good work though much better than what I could accomplish. :wink:

Hi Bernhard,
I think you might be correct. I was able to find a clip taken at 400x brightfield. What do you think? Frontonia? I added the video at the top of the page at:

Here is an image extracted from the movie:

Thanks again for any identification ideas.

Okay. Looks like I found a matching image at Micro*scope which shows some Frontonia with testate Amoebas inside.

Identification solved.

Thanks Bernhard and everyone.

Tom.. I agree, your videos look great.

It is amazing what they can cram inside. I have come across a few that just made me laugh!
Sort of like Thanksgiving and Christmas dinner rolled into one!

Hi,

well, unfortunately, we can't see the slit with the mouth for certain, but I still find Frontonia very likely (all the more seeing your 400x video)! It is closely related to Paramecium, by the way.
