Abstract: | Miamiensis avidus is a marine polymorphic scuticociliate that undergoes microstome to tomite transformation when nutrients are depleted. This transformation takes place as a result of two consecutive divisions and does not involve a cyst. Tomitogenesis was induced by nutrient deprivation. When returned to nutrient medium tomites transformed into microstomes. Changes in population were noted at one-hour intervals. Tomites of Miamiensis avidus Ma/2 are compared to dispersal stages in other scuticociliates and hymenostomes. |
