Description
Vertical movement of the moon jelly Aurelia aurita was investigated in the southwestern area (5.8〜9.4m deep) of Omura Bay, Nagasaki. We examined the influence of attaching micro data loggers on the behavior of six moon jellies in an aquarium. No significant difference was observed in mean bell pulse frequencies in experimental animals vs. controls (p>;0.05). In addition, micro data loggers remained attached to the bells for at least 5h. From June to July and October to November, 2009, the vertical movements of 10 moon jellies were recorded in the field. Moon jellies that were tracked remained within the 2m-depth layer during the daytime in June, but were closely associated with the seabed in October to November. Eight out of 10 individuals exhibited the initial descending behavior when released, which might be a reaction of the moon jellies to handling and/or micro data logger attachment.
