This video shows a pretty large group of Stentors feeding. One of the interesting things to me is that one of the stentors has ingested a couple of Difflugia. I hope it can break down the test of those Difflugia before the remains are ejected from the cytoproct! In this collection, there were many stentors that had ingested different sized Difflugia, so it must work for them. Toward the end of the video, there is also a smaller stentor amongst a pair of much larger stentors.
