Can anyone identify this Unidentified Floating Object I found in a West Vancouver muncipality pond 10 days ago. I think it's botanical and not animal. Jelly like sac about five or six inches in length. Firm texture with what I can only describe as almost fluorescent green objects looking like empty green grape skins. A friend said frogs spawn but I did not think so. There was another such object, but I could not reach either. I managed to tap one with a twig and the jelly had a surprisingly firm texture. Any information will be gratefully received.
