Two nights ago we decided that we would take a swim on the course. We're not really triathletes, so our goal was to swim a mile, as opposed to the 2.4 miles that the Ironmen and women swim.
Triathletes chill out after the training event |
We arrived at the pier to discover that a training event was just wrapping up. There were tents providing the competitors shade and sustenance and lots of buff bodies, bikes,etc. Every now and then, as we changed into our swimming gear, a runner would come in to cheers and applause. Soon we were in the water, heading out on our own Ironman swim.
As we swam we were careful to stay out of the lane used by the training swimmers.
As I reached the last of the usual swim buoys, now dwarfed by a huge orange Ironman buoy, I paused and looked for Sandra. She had stalled about ten yards to my left, obviously looking at something below.
Overtaking the Jelly |
Not wanting to miss out, I adjusted course and swam towards her. Suddenly, I found myself overtaking a large pelagic jellyfish. I had admired this species while studying John Hoover's Hawaii's Sea Creatures. Knowing that it was pelagic, I had little hope of ever seeing one. Wowser! The jelly was cruising along slowly, rhythmically constricting the edge of the bell. It took only a moment to summon Sandra, who was equally impressed.
The jelly was at least three feet long, counting its rope-like tentacles. The bell was a luminous purple with a light brown and black fringe. Near the bell, the tentacles increased in size and changed form red to a creamy ivory. This was an incredibly handsome animal!

And the jelly was not alone. There were several fish living among the tentacles. The smallest were immature Golden Trevally, which look quite a bit like Sergeant Major Damselfish at first glance. Also among the tentacles were two filefish. The larger of the two was about six inches, the smaller about half that size. The smaller guy stayed deeper in the tentacles, at times nosing right into the bell. Both had a white honeycomb pattern superimposed over a brown base with black spots at the center of each polygon. We swam around the pulsating jellyfish with its curious cargo, taking lots of pictures while keeping a respectful distance from the large tentacles.

On the way in, Sandra showed me the school of scads. And I got my picture taken with the Ironman buoy. Top and bottom, these large orange buoys bear an admonition that they are not to be used as a life saving device. On the side of the buoy are the logos of companies who produce life saving devices. Apparently it is up to the swimmer to make his way to shore and then purchase his lifesaving equipment. Drowning is not in the spirit of the Ironman!
Iron Jeff Flips You a Shaka! |
Back at Casa Ono, we got right to work.. We found the jelly in Sea Creatures right away. The filefish was a different matter. It was clearly the shape of our friend Mr. Scribble, but none of our books showed a fish with that white honeycomb pattern. There are two rare filefish in Hawaii, Garrett's Filefish isn't pictured because it is found at extreme depth. The other, the Unicorn Filefish, has little in the way of markings and really isn't the shape as Mr. Scribble.

Team Mango says, "Find a new fish!" |
So its not a new fish for the state, but that immature has never been photographed before in Hawaii. And its pretty cool if you can stump Dr. Randall, even for a few minutes. The Great Oz gave us some sites to send our exceptional pictures to, so there is still a little work to do.
Thanks for sticking with me on this long tale and we'll see you at the race.

Hi Jeffrey,
ReplyDeleteI am researching the jellyfish from your photos, Thysanostoma, can you tell me the exact date and location where you found it? If you like you can post your sighting on www.jellywatch.org so we can keep track of these guys.
Thank you,
