The dwarfs had tiny, proportionate feeding organelles and the number of lateral stripes was about half the normal, indicating the morphological adaptation to decrease in size. Johnson had found that such dwarfs undergo no irrever- sible changes and are capable of complete recovery, growing and dividing when later fed. I demonstrated that fragments of these tiny stentors were capable of normal oral regeneration.. Fig. 72. Largest S. coeruleus compared to smallest individual in starvation culture.
