Invisible Oceans Founder's Collection: Invisible Oceans #98: Rhizostoma I

We have only ever seen this species of rhizostome jelly once in all our years of working at Lizard Island Research Station on the Great Barrier Reef of Australia. It is clearly a plankton feeder and not unlike some others that we filmed but its flat top and tendency to hug the surface, imply that it is a cousin, not a direct sibling species.
