I was fishing the other day and could have sworn I saw a jellyfish. I would have put money on it. It was a little one, no bigger than a half inch across. Well I did some research and come to find out, there are fresh water jellyfish found everywhere in Indiana. They are very small and can not sting humans. Just thought this was kinda cool. The article says that most of the year they are just polypops on the bottoms of submerged logs and rocks. But this time of year there are actually jellyfish out and about. So next time you are on the water this fall, keep your eyes open for them!
