This came on some Fiji rock that I have had for abouth 6 months. They look like jellyfish attached to the rocks. I think they are somekind of coral, just wated to get some more info.
well i apologize for any paranoia i may have caused by misidentifying this pic. i was only giving my opinion, which has been known to be wrong at times. guess i've still got a lot to learn about IDing things yet.
