The Boston Harbor Jelly Infestation

We are already a week into the summer and the harbor is jumping with excitement. Michelle, LaToya, and I have been running the program at Piers Park and Courageous Sailing Center at Charlestown. As you all may have noticed, moon jellies have been swarming the Boston Harbor this week. Everywhere you look, you can spot one. Also, if you look closely, you can spot some minute differences in the seemingly identical jellies. The kids at Courageous have noticed several of these interesting differences. Most moon jellies have four visible rings on the top of their bodies. However, we have seen some with 3, some with 5, some with 6, and even some without any at all. These rings have also been different colors too. The average ring is white, we have seen rings with blue, pink, and orange tints. Out of the water though, the rings become transparent. Although all moon jellies do not look the same, it is crucial that you do not mistake these jellies for lion's mane jellies. Both jellies sting you, but people cannot feel the moon jelly's sting because our skin is too tough. On the other hand, the lion's mane jelly's sting can be very painful. Do not fear though, you will probably only run into moon jellies this summer.
