Unless you know my attitude on Seagulls...the references here are a little [read: A LOT] opaque. Nonetheless, I encourage anyone tuning into raineworld to watch the embedded Youtube video Jellyfish. It's absolutely excellent. It's done by Steven Haddock *smirk* of the Monterey Bay Aquarium Research Institute and the images are beautiful.
Anyway, watch. And be amazed. The video link.
