Zooids....yep!

Those jellyfish like creatures in me video are called Zooids. They come around every year bout this time. They usually atatch to the pontoons pontoons (ha) or any other solid stationary structure. The are breeding..........
They good creatures. Water quality has to be good for them to survive. I have to quit peeing in the water when theys show up. As you can see in the video, they dont hurt fishes. They snack on plankton. They show up on the "fishfinder" as big fishes. If you just happen to run into one of them (colony actually) it is just like it ain't nothing there. Just mush. It can really fake u out this time of the year. Just to let u know.

I wondered what they were. Nasty looking things.
