| Abstract: | In SCUBA-diving monitored field experiments (Flensburg Fjord, 15 m, 1981) and parallel aquarium tests,the behavior of Metridium senile under anoxic conditions and its oxygen-deficiency resistance were studied. When oxygen is lacking the fluffy sea anemone diminishes body surface, and then, successively, shuts off most energy consuming activities. By means of this strategy, 50% of the tested individuals survived 3 weeks of total anoxia. |
