Yesterday I got some water from a pond. Are these stentors?

Re: Stentors?
First one is a rotifer (I'll leave it to someone else to figure out what kind!)
Second and third are Stentors. The third one has symbiotic algae, no cortical pigment granules and moniliform macronucleus, so is probably S. polymorphus. The second one doesn't unabmbiguously show the macronucleus, so identification to species isn't possible (from here, it looks like the mac is probably moniliform, i.e. "like a string of beads", but I'd prefer to see it more clearly).
Nice videos!
