1. From the video footage it appears that stentors are selective about what they feed on. Using their mouth cilia, how might potential prey be evaluated for suitability?

2. When stentors swim, they turn into a football shape:

(a) What does this say about their attached shape like a long trumpet? Which shape is the "natural" one?

(b) You may have noticed that the stentors rotate while swimming. Can you think of why this happens? Compare the swimming Stentor to the swimming Euglena, what is the same and what is different?

(c) What cause a stentor to detach from one location and swim
