I don't know what these are. I was kayaking 1000 islands in Cocoa Beach today saw this web in the mangroves & thought they were egg sacks, in a blink of the eye they dispersed all over the web. The area is still pretty devoid of birds since the fishkill last spring, saw a couple ibis, 2 osprey & a belted kingfisher.
Hi Frank, I do that every time I go there, saw a little snake earlier in one. The water looked pretty clear, mangroves looked healthy I could see my paddle end down about 2 feet. I never thought of that, Ira, but I was holding on to a branch & probably jiggled them severely.
