Coral Gardens Dive, Flinders Reef, Morton Island
We found it in the sargassum. It was definitely on the move. The green/yellow part of its body was not soft, but not rigid. Up close I can see its slimy body moving ahead of it. It appeared to have two pods, one on each side of the organism. I have not been able to find any animal similar to it. I don’t think it is a jellyfish, but it could be a Gastropoda. When not moving it looked like a tiny seed. About 1 cm long.
