Is It Live……

……or is it just a piece of floating flesh?  I saw this LWT (little white thing) floating near some rocks at Mauna Kea resort.  At first I thought it was just a piece of floating flotsam (or is that jetsam?), but as I watched, it repeatedly attached to the surrounding rocks, then floated free again.  Though it’s not seen clearly on the video, it did seem to have a (very small) snout and mouth.  The fish that are nipping at it seem to take a bite and then stop….?is it toxic?

Don’t know the answer to any of this, I just present it for your viewing enjoyment:
