Scores of them were flying through this morning...and in recent days.
I picked up a bunch of garbage while in the ocean. When I was sorting it out for the rubbish bins, I found that this shell had hitched a ride. I tossed it back in the ocean.
Seagulls drew my attention. As I looked through the camera, I noticed the fin pop up briefly. That's all I saw.
There was a large "platter" of loose Brain coral (third picture) sitting on top of a boulder that is part of the jetty. I picked it up to examine it and found these anemones on the underside. I could not determine where the loose chunks of brain coral came from.
