Comments | Swimming around Green Pond's circumference every summer for the past 20 years, I have observed (except for the past 3 years) and twice collected specimens. On Sept. 8, 2020 I counted 250. I have not always observed them in the same place, but it seems most often over the deepest parts of the pond, whichg I estimate to be 20-30 feet deep. That Green Pond is 200 feet above the surrounding man-made (1920s) lake and is spring fed, it is not obvious how the jelly fish arrived at the pond from the Yangtze River. western parts of pond about 1-2 feet below surface. Temperature 78-80 degrees F. |
