Abstract
Strobilation can be induced experimentally by the raise of temperature; minimum effective range is 20 - 22 [degree]C. The range coincides with the temperature in habitat where the earliest appearance of ephyrae is noticed every year. For the induction of strobilation, previous treatment of scyphistomae by lower temperature is necessary. The individuals which have once failed to react to 20-22[degree]C can no longer metamorphose by a further raise of temperature unless they are exposed to the lower temperature for appropriate period of time. These experiments have been done by the use of individuals with symbionts, zooxanthellae, which induce strobilation of zooxanthella-free scyphistomae.
