Cyclomorphosis is not a form of dormancy.

Dormancy is a state of reduced metabolic activity and physiological inactivity in response to unfavorable environmental conditions. Hibernation (winter dormancy), Aestivation (summer dormancy), and Diapause (dormancy in insects, often cued by photoperiod) are all examples of dormancy. Cyclomorphosis refers to seasonal or cyclical changes in the morphology of organisms, particularly plankton, in response to environmental factors like predation pressure or water turbulence, rather than a state of inactivity.

Cyclomorphosis allows organisms to adapt to changing conditions over time, often improving their survival chances against predators or adapting to different water conditions throughout the year. It is an active adaptation rather than a state of metabolic suppression.
