A couple of videos of a Stentor consuming Rotifers

Using an Omax microscope and an Amscope MU300 camera, I captured some video of a Stentor consuming one or more Rotifers. I was using 10X and 20X objectives.

This may be typical behavior for the Stentor, but it was new to me. It may be that the large number of Rotifers near the Stentor make this sort of thing inevitable.

Thanks, fonakta! Any time I am looking through a microscope I'm looking for something to turn into a video.

Thanks, Carlos!

I guess I am fortunate that Stentors are common in a little nearby pond. Several people who have been in the microscopy hobby for years have told me that they have never seen a Stentor in the pond water samples from nearby sources.

Thanks, Rogelio! I have enjoyed your photography as well. I just finished some video of Stentors that I will upload over the next day or so. I just discovered that in a darkfield video I made of a "large, pink ciliate" some days ago, the pink color of the ciliate was due to the illumination. I now believe it was just a common Stentor coeruleus. In the video I just made, two Stentors have the common blue-green color with brightfield and then, when I switched to darkfield, they were the same reddish pink as the "large, pink ciliate" of the earlier video. It's so easy to be fooled, especially when one is so new at microscopy like I am.
